I admit that the more I learn about my DNA matches, that the more that I want to know about my DNA, as I have a huge number of matches from one paternal line far more than others, or maternal line matches that technically I should not have, but do. Consequently, knowing how recombination may influence this result is important, especially along with other factors. As the supermarket logo here states: "Every little helps!' Thanks!

This is a good explanation of a somwhat-confusing topic. Thanks!

A future for individuals

Very clearly depicted. The n=92 before cell division (human) is often ignored.

This is about frequency of recombinations... What about cM of such recombinations?

A female baby is born with all the eggs she will ever have, roughly 400 I think. So the recombination has happened during gestation, correct? Sperm are "manufactured" in the adult male body in an ongoing process. So sperm recombination is happening in "real time", correct? I very much enjoy your DNA videos; I have learned a lot from them.

Thanks for another interesting video. If you need more data to play with, I have the data from three of my children, all full-siblings, that I would be happy to share with you. I visually phased them, at least the way that I understood to do it. There may be mistakes, but I have their GEDmatch numbers in the document, too. Then, I have a chart in the document that shows how many segments they have maternally or paternally per chromosome, as well as a list of unrecombined chromosomes broken down by grandparent. If you don't need or want more data for this project, no worries. I'm glad that you and Devon have this channel and teach us so much. Going back to school to study genetics is not an option for me, but I enjoy learning all that I can about it! Have a blessed week.

To test if the Y or X chromosome is affecting the recombination rate somehow, we should study males with Klinefelter syndrome who have inherited both their father's X and Y.

Very interesting video! So to clarify, are recombinations the segment swaps between the chromosomes I got from my parents, that I then pass along to my children, who then swap the segments around before they pass it along to their children?

So the difference in recombination frequencies between maternal/paternal explains why the number of segments can be helpful to determine the different relationships for close relatives?

What's interesting with this is that I know that my dad's side I expect to see Iberian show up and it does throughout the Chromosomes but I noticed that on Chromosome 11 I have it seems the highest and longest lines of Iberian than on any other Chromosome, I also see some Basque there too. So can I assume that that's my dad's side that shows little to no recombination.

Has there been any update to the Visual Phasing Chromosome Selection Matrix? The latest one I find is from 2018.

why wouldn't we distinguish between crossover events in meiosis and recombinations, which are different as a result of second sell division and selection of only one variant after it?

Could Celts who interbred breed the anglo saxon out❓

I'm confused by the histogram chart showing the number of paternal (blue) and maternal (pink) recombinations, as it suggests that the statement made about there being occasions with NO recombinations not being true. What am I missing?

Can X and Y chromosome recombine, say parent has Haplogroup Q Y-DNA but no Autosomal Amerindian/Siberian marker, but somehow that marker ends up in the female offspring's autosomal DNA?

Interesting different chromosomes have different recombination rates. In researching genealogy would you expect very distant cousins to show up more related to y chromosome heridity?

However, it must also be taken into account that if nine chiasmata occur in a chromosome, it is not necessary to consider exclusively one of the two sister chromatids that make up the chromosome but rather both, therefore those nine chiasmata could be six in one sister chromatid and another three in the other arriving thus to nine chiasmata on chromosome number two. We must also take into account the interference of the first chiasmata and therefore it becomes normal for the other chiasmata to occur in the other sister chromatid.However, it must also be taken into account that if nine chiasmata occur in a chromosome, it is not necessary to consider exclusively one of the two sister chromatids that make up the chromosome but rather both, therefore those nine chiasmata could be six in one sister chromatid and another three in the other arriving thus to nine chiasmata on chromosome number two.

I wonder if some of this might be the reason why I seem to have more matches at Ancestry DNA to certain ancestral lines and not others. I'm a guy and in some cases I think it might be due to there not being as many participants that are descendants of those families. But it does seem somewhat interesting that I have a lot more matches with my dad's paternal and maternal Alabama families than some of my mom's ancestors mostly on her maternal side. I have a lot of matches with my dad's Trucks and Cottingham families (Bibb County, Alabama). And a lot of matches with mom's paternal Piemontese (northern Italian) families and a lot of matches with my mom's United Empire Loyalist (Fox and Wigle) families. But on my mom's maternal Mid-Atlantic and New England families there are a lot less matches than I figured there should be. Especially with Baker (my maternal grandmother's mother's maiden name). Which has a significantly smaller number of matches with Thru Lines connections and (to me) there should be a ton of them.
