I share 50.8% with my father and 49.2% with my mother. I also share 27.8% with my grandmother from my mother's side and 22.2% with my grandfather. And 38.2% with my brother.

Fascinating! Thank you

excellent explanation! thank you so much!

Thanks for the clarification

Thanks Andy great explaination🧬🧬

Wonderful explain about DNA 🤩

It took me forever to understand this until I realised it's just from the fact you are going from two person's amount of DNA to one person's amount of DNA so half of it has to be chucked out simple as that.

Well explained

So very interesting !! Wow, I didn't know the grand-parents mixing could be so heterogeneous at chromosome level. This maybe explains why I am the spitting image of my father's mother. This and another phenomenon : the recessive genes. You may have inherited such and such genes form both parents, but it doesn't mean they are gonna express if they happen to be recessive... Well, not too sure about it, though. If I get 23 from both parents (= 46), and I only can express 23, it means half of the 46 will be silent ??... 🧐

My father had two half-brothers: one on his father's side and the other on his mother's side. The other brothers would not share any DNA in the 22 chromosomes.

Thank you!

Hi Andy, All 4 of my grandparents have all passed away with only my Maternal Grandmother tested and I'm wondering is there a way to find out how much DNA I inherited from my Grandparents?

What testing company shows these specific recombined percentages?

Hello Andrew, I had an account with Ancestry for 4 years. It never brought up my Paternal side. Not just my living family members but actually never displayed ANY Paternal members period. I have called the company and they want me to retake the test. Here's the kicker. My aunt who is my fathers only sibling also took Ancestry test. Her Maternal side has not shown up... weird right? Since 99% of DNA is all the same do you think I will get a better result if I retake this test? Thanks!

Ummm Andy there are not video links at the end of this video. You are still just pointing at air when we view.

So what about full blood siblings?? It’s just the luck of the draw basically & we get different combinations?

Hello I wanted to ask what was the best DNA company to use for researching if you may have children that you were not aware of. For example.. being in the military.. im asking, I think I may have a son, I never knew existed. He's my mini-me genetically and behaviorally..but for clarity I wish to find out the truth for peace of mind. Thank you in advance.

can i inherit my great grandparents height genes? Like mostly there short same with my dad but my grandmas dad from my moms side is tall like around 6 foot tall, and I mostly resemblance my moms side Could I get that tall from my great grandfather? My father is 5'8 and my mother is 5'5

I look very similar to my maternal grandfather. Does that necessarily mean I have a lot of shared DNA with him? Or could I just have a little but have inherited certain genes?

1:31 22 Divided by 44?

I have a question. My great grandmother on my maternal side was half Chinese. I did a DNA test with Ancestry and it showed I have 4% Chinese. I know it’s from her because of my 8 great grandparents, I know for a fact she was the only one who had Chinese. Is that a normal range for me? Since my great grandmother was APPROXIMATELY 50% Chinese, would me being 4% be accurate? Or at least fit within the normal range of inheritance? Thank you in advance. 🙏

I got a grandparent/half-sibling/avuncular match from someone unexpected. We're showing sharing 22.61% DNA (1639.49 cM.) They're definitely not a grandparent. That leaves a half-sibling or avuncular. Is this level of DNA possible for a half uncle or a nephew from a half brother? That's the only type of avuncular match this person could be to me if they're not indeed a half-sibling.

My brother doesn't show as a match in the group I share with my son. Can he still be my brother?

I've been working on my DNA matches in Ancestry. I have a 2nd cousin once removed that I match at only 13 cM. How is this possible? I look at DNA painter and it says 0% chance. My mom's DNA is in Ancestry. She matches this 2nd cousin at 129 cM. That seems right. How can the drop off be so big from my mom to me in this case?

I have a situation that is really baffling me which led me to your KZfaq channel. My Grandmother and her ancestors were all from German and Norway but on Ancestry and 23 and me I am 0% German or Norwegian and I don't understand why. I have DNA matches on Ancestry where we share 4th Great Grandparents but they are all on my Grandfathers side and there are no DNA matches on my grandmothers side. There are also no matches more recent than 4th GG. I don't believe anyone is adopted because of family resemblances so how could this be possible?

I have 14.6 procent of my grandmothers dna is that normal the mother of my father? Does anybody know

I got 30% from my paternal grandfather, that’s quite a lot I think.. Now what I actually find weird though, is that I got 19.3% from my paternal grandmother.. how does that even happen? I tested both grandparents and myself, and I have a cousin from the other side of my family who is pretty accurate around the 12.5 mark. Did the rest 0.7% not get recognized because it is mutated enough from one of my grandparents (or both)?

I dont know who my biological father is. My 19 year old daughter just had an ancestry dna test done. Its come back 24% irish. There are no irish relatives on her dads side and no irish on my mothers side. Does this mean my father/ daughters grandfather was possibly irish or maybe one of his parents were?? Hope this makes sence as i struggle a little bit with understanding how it works xxx

So, you're saying there's a rare possibility that I could inherit 50% from one grandparent and the other completely left out?

Is there ever any true variance with the 50% shared with parents? I ask because although Ancestry says 50% between me and my father, MyHeritage only shows 49.6% between me and my mother. MyHeritage also shows less than 50% between me and each of our tested children: 49.9%, 49.8%, and 49.7%. It is the same on MyHeritage for my husband and his mother, 49.8%, not 50%. Ancestry shows all of these relationships as 50%. It doesn't make a difference whether it was a native MyHeritage test or a transfer. All show less than 50%. Why the difference between the two companies?

It's weird I look 100% Mediterranean ,so does my dad's side. But our lineage is from France Paris/latin quarter, wallonia , champagne and norde pas callais but we can pass for Greeks or Italians it's crazy . I'm confused

Oh😮

I share 22% with my maternal grandfather... and 11% with my maternal grandmother. This seems impossible. Aside from chimerism, is there ever any way for someone to share less than 35% of their DNA from one set of grandparents, or only 11% with one grandparent? I can't imagine there is, but... The only way both of them could be related to me without my grandmother being my grandmother is if my grandfather impregnated her much older, married-with-kids sister, who lived in a different state, a couple of months after he married my grandmother. And then my great-aunt would have had to admit what happened or come up with some other excuse to give my mother to my 20 year old, newlywed grandmother rather than simply raising her with her other kids and passing her off as my great-uncle's. And then my grandmother would have had to be so okay with this, that she would go on to have several more children and 50+ years of a very stable, loving marriage with him despite divorce very much being an option from both sides of the family. AND my loudmouth family, which loves to drink and dig up old skeletons during family reunions, would have had to keep it a secret for decades. My great-grandmother was well into menopause by the time my mother was born, and I don't think they had much contact with extended family so I don't think my grandfather would have even met any of my grandmother's cousins or other close relatives. There just simply aren't other options for who my grandmother could be. So, faulty results? Medical anomaly? The most nonsensical case ever of someone secretly raising their sibling's kid? I really want to make sense of this, any real suggestions are welcome.

What about people who are mixed? You aren't going to inherit as large amount of dna. For example, I am 3% African per Ancestry. My great grandma appears to have been mixed. I am still working on this. My uncle gets 7 % African or so. This would be his grandmother. We also have a great and great great grandpa from Austria Slovenia. I only got 1% Eastern Europe and Russia which says includes Austria and Slovenia. Shouldn't I have more than 1%??

My sister looks just like our grandmother and we both took a DNA test and she shares 37% of her DNA and I only have 25%! It just depends who you favor the most I guess.

How are you able to tell that the blue line is your grandfather? Did you do a DNA test on him?

If you have 50% of the genes of each parent, then you must have the 25% of each grandparent.

How would it work when you come from a large family? I have 12 siblings. Half are full siblings and half are half siblings.

I would like to know why you didnt focus on the Maternal Grandparents instead?

Hi am i sharing my dna with my all greatgreat-grandparents?

I have yet to take a dna test for ancestry, (multiple reasons). When looking at the nationality results from some of my Daughters siblings I see that they average 4% Chinese. My Ex is Samoan. I know it’s a long shot but is there a possibility of knowing how far back that 4% Chinese is? My side of the family was easy, no surprises but we thought it was cool to find tiny percentages from Asian countries. (Yes we know there tend to be kinda high percentages mixed with Asian and Polynesian nationalities. We’re just curious if it could be found out how far back the Chinese dna was.

And wich dna I need for this method? My 4 grandparents are not alive anymore. My Dna is on My Heritage and also from my daughter. Can I get this kind of results only with our dna? Great video again. 👍👍

To get these percentages, I assume that your parents and grandparents must be DNA tested?

This is where I get lost. When something is all black and there is no match across the dna bar, how do you know which one it is pointing to?

Does this mean its theoretically possible to not be related to one of your grandparents?

Hello can you please tell me how to learn my ancestry from my grandmothers father specifically? Thank you i am male. Grandparents are gone but i have male uncles, if that helps (Male uncles ha im leaving it)

why is it I don't have central and eastern china ethnicity yet my paternal great great grandfather is from china?

So you will never really know from where your grandparents reqlly came from

22? Don’t you mean 23?

My parents and all my grandparents are dead except my maternal grandma and she gas Alzheimer's in a nursing home. So I will never know.

2 plus 2 is not 4

The milkman? Maury show is more fun

Huh? ..you have 4 grandparents. ..and so, you do not know if it is paternal or maternal grandparents match without their DNA data.

Universal.org

The 50 percent doesn't always show up My Heritage.

Not a match can also be mutated between the two enough to be different

What if 3 of your 4 grandparents were 100% Irish. And one of them was German and French. But your DNA results show zero German and zero French. Confusing

I came to the conclusion that we are only related to half our grandparents since we only get one set from each and unless it is mixed we only get half of them.

Me who has 2 fully European grandmothers, and 2 fully Asian grandfathers: "👨‍🦲"
