It's gonna take my smart ass a whole semester to really understand his 15 min lol. Gonna have to repeat this a few times to really be comfortable with the info is all.

🤣🤣🤣🤣

@@gryndkommeted1362 thats the way to do it ha

What is this subject I mean where do they teach this kind of stuff I was just here for some info on breeding

😂😂😂😂😂😂😂

Alright now TRUE comments like this'll get you put on a watch list . GREAT COMMENT

True

Dumb dropouts post stupid comments on the internet. College professors are often well accomplished outside the classroom. And this is literally all repeated content. You think he invented these concepts? No he is merely repeating information he learned himself.

Math? I'm okay at 2 plus 2, but much beyond that give me a calculator. I used to be decent at reading Louise L'Amour Westerns though. To bad that don't make me better at math.

thanks

@@APBT-Bandog you're welcome

Good question.

Yes F2

Hmmm interesting where can i get more of this information?

@@Sk-zb5jm any decent college text book on genetics.

Better chance of getting faster dogs if u breed the fastest dogs

I've bred half brother half sister before. And I've known many breeders who have. The pups will take after the grandmother in your case. They won't have her intelligence because that declines inbreeding but they will be strong in her characteristics and they will imprint those characteristics on their offspring. However.., inbreeding magnifies the bad characteristics also. A trait like growling another dog to protect food can turn into tearing each other's ears off over a bad look. My advice is don't inbreed unless they are the last two of a kind. Find a stud that's distantly related but not too close. Outside of 4 generations. As long as they are similar in type their offspring will be more than sufficient. Remember everything purebred is already related. So inbreeding should only be done with mutts to create a new line.

Don't do it. Go to another breeder for a different dog. Your risking it, because the lines are too related. You need to go outside the gene pool.

"Ever"...yes, I do see a time and place for it...but it should only be done after a line is proven to be at very low risk of carrying genetic disease by observing its production history AND ALSO when the individuals that will be bred are of exceptional quality. That said, I do not like posting this because many people will read this and start doing full sibling breedings thinking it is ideal, when they have not first done their homework...and that is a good way to produce disastrous results. Despite decades of breeding that we have done, I can only recall doing a full sibling breeding twice.

That would be line-breeding; however, if you should do it or not depends on the bloodline. What do you know about it? Are there genetic defects? If so, who has them? You have to study the line. I don't have the time to do that work for you. Instead, I can only tell you what you need to do. There are no short cuts to doing the research and study required to becoming a good breeder.

What aboit other health shit

Never give up!!!

All dogs have a COR of 50% of their parents....so your comment is incorrect. I suspect you are thing of COI, which is the coefficient of inbreeding...I have gone as high as 25% COI without any issues, but when I got to 37.5 COI I had a hard time getting a litter of pups out of her. If I used a male, I think that would have still been okay. That female had a COR of 87.5%

I did indeed mean COI. Thank you for replying. I didn't realize the two terms weren't interchangeable. So, if one bred let's say a grandparent to their grandchild (12.5% COI), what would the COR of the puppies be? Assuming the grandparent is the father, and the grandchild is the mother. The puppy would have 1/2 the grandparent's DNA from it being the father, and 1/4 of the grandparent's DNA from its mother the grandchild, correct? So the COR between the puppies would be (1/2+1/4) = 3/4 or 75%? I feel like I'm making a mistake still.

American Sentinel K9, LLC i have a Male with the same father on both sides and a female with that same father on one side so that means too many times for them to breed?

@@neilsimpson9963, it doesn't work that simple. You have to look at the quality of the dog, and the health in the line. There is no short cut to learning genetics and performance testing. Asking a specific question won't give you the knowledge you need. If you need to spend more time learning more on the subject, I would recommend getting a book on the subject.

@@neilsimpson9963 the male cannot have a father on both sides. I guess you mean the male was out of a father daughter breeding...OR same grandfather on both side?

sure, half-siblings is a type of line breeding, and if the common parent is a good dog, it can work well. Just make sure the other parents that are not shared are solid in any areas the common parent could be improved on.

correct. thanks

Nelson Girao line breeding requires breeding father to daughter, granddaughter, great granddaughter, etc. Thats why it’s called Line breeding, because it’s genetically a straight line from the original sire. And each successive breeding imparts more of his genes into the offspring.

@@ShipWreck54 Doesn't line breeding refer to breeding collateral lines, such as cousins? Father/daughter or full sibling/full sibling are usually referred to as inbreeding rather than line breeding. The closer the relationship, the more careful one must be to cull less than ideal animals. Even so, there will always be some long term risks from the Bakewell model, although it remains popular because it is fast, effective, and requires relatively few animals. However, some more cutting edge breeders argue for a slower approach that emphasizes assortative mating over inbreeding or line breeding since it does not reduce the breed's genetic diversity as much.

Depends on the line and how healthy it is.

There is always a chance, and as one breeds tighter and tighter (which increases homozygousity), chances increase to see any type of genetic defect.

American Sentinel K9, LLC thank you

Yes, fish too.

Are u crazy hahahahah

Mother to son not good. Dad to daughter is ok

@@Siberianhuskypuppy seem that will take me long time. How about brother and sister

Make me laugh son mother is not ok but dad to daughter is they are the exact same relation 50 percent to answer the first question 50 percent is too close in most people's eyes half siblings (25 percent of less)

Have any of you watched the severity of diseases that that plague a purebred, if you want healthy beautiful dogs that will be healthy then stop inbreeding, I lost my beloved cocker spaniel from dcm due to health issues from inbreeding, I'm not ever buying another akc after learning that there inbreed just for show standards, not many people do shows, the dogs health should be first.

U have your own blood line

You’re your own grandpa

The dog is a product of complete outcrossing of unrelated individuals.

Outcrossing is mating of unrelated individuals. Linebreeding is mating of individuals that are related less than immediate family. Inbreeding is mating of individuals within the immediate family...meaning individuals with a 50% COR, such as a mating between mother-son, father-daughter, or full siblings.

You would have to know the grandfather well...what were his strengths and weaknesses and did he have any offspring with any weaknesses.

@@APBT-Bandog the grandfather/ father has amazing Traits. He has everything that I'm looking for in a Cane Corso. That's why we got our male. We just found out that his father is the grandfather to our female.

While it may appear that way for expressed traits, in reality it doesn't work that way, simply because if one considers all the loci and traits, and not just the highly visible ones, there are simply too many loci. Frequency approaches probability when the sample size is very high.

@@APBT-Bandog I guess my confusion comes from human siblings dna testing. If the father is Irish and the mother is Mexican, one sibling can have 30% Mexican dna while the other has 70% Mexican dna. Wouldn’t this be the same in the puppies? And therefore they aren’t getting an equal 50% of their dna from each parent?

@@Loarnold That is based on the markers used in the testing, not the absolute measure itself.

@@APBT-Bandog ok but why does a genetic dna test show my sister is 70% of my dads dna while I only have 30%?

​@Loarnold maybe your mom has some Irish DNA too from way back k almost like how some whites in America have acrican genes but don't look african at all

evaluate both dogs. Make sure they and their parents are free from genetic disorders, display the traits you desire, and perform well.

agreed; however, generally inbreeding is the term used when there is a 50% relationship such as parent-offspring or full-siblings.

Half siblings share one quarter of their genes just like uncles and nieces, so I expect the outcomes would be similar for these pairings.

Any relationships with 2 generations between them

I heard that but I wanna be better so I'm having to watch this 2 times now lol

It might be easier to understand if you visualize it as pie chart, as he briefly did on the drawing board early in his lecture. Also, if you trace the genetic relationships remembering that at each step the relatedness drops by half, for example, sire to father to father's brother to father brother's son, that is three steps or 1 divided by 2 to the power of 3, that is, one eighth, the relatedness of the two first cousins. That is, the son will share have the genetic pie chart with this father; then the son will share one fourth of the pie chart with the father's brother because even though the brothers share half their genes with each other and with their sons, it is not the same half, just half of a half will be in common between uncle and nephew; and finally one eighth of the pie chart will overlap with his cousin. Or to think of it another way, 2 first cousins will each inherit one fourth of their genes from their 2 shared grandparents (one eighth from each shared grandparent=one fourth), but not the same one fourth. About half of the genes they inherit from their grandparents will be shared (one half of one fourth=one eighth), and the other half of the one fourth will be non - overlapping between the 2 cousins.

Just hit the three dots in the corner and select 0.75 for a slower speed of play.

yes. That is line breeding.

Outcrossing is mating of unrelated individuals. Linebreeding is mating of individuals that are related less than immediate family. Inbreeding is mating of individuals within the immediate family...meaning individuals with a 50% COR, such as a mating between mother-son, father-daughter, or full siblings. If you do a full-sibling breeding, make sure both siblings are excellent and their parents and grandparents are also excellent. If so, then you will likely be okay.

RC (COR) = 50% COI = 25%

Depends on the quality of the dog, its ability, its health, the health of the offspring, and the pedigree.
