It was a general statement, it would be hard if not impossible to argue against something that has been proven time and time again for the better part of the last 80 yearsThanks! I didn't want to argue with it, just to see & understand it
Would be interesting to see if this DNA test is able to detect the Chinese Oocyan allelic mutation. The Chinese allelic mutation was an independant event caused by the same retrovirus insertion but on a different insertion site..
I don't want to argue with the stated results, I want to understand them. When there is a reported range of 3 to 8 centimorgans between two genes, the implication is that there are about 4 million base pairs in between.
The article I was reading that stated P and O were adjacent had a chinese author. I have not yet found it but will post it when I do. Meantime, the evidence is very clear that P and O are NOT adjacent, but instead are separated by a rather large region that is more than normally active in terms of crossovers. It appears there are about 20 to 30 genes between P and O. I want to nail down that "20 to 30" number a lot better.
I’ll be seeing the people again next Saturday. What would be a simple way to tell them that their info is false?
A simple explanation?
"Yes, you can get some green eggs from crossing the F1s.When you cross a blue layer with a brown layer, you get green eggs. And if you breed a f1 hen and a rooster of this cross, you can‘t get more green eggs. They are only blue or brown.
Don't forget that a small percentage may lay white eggs."If the F1 hen gives the genes for brown, and the F1 rooster gives the gene for blue, you will get some daughters that lay green eggs!"
I would put it this way: When 75% of the expected progeny wiĺl inherit the Oocyan mutation and most of them will inherit at least one of the brown egg shell genes. The chances of getting green eggs of all shades is pretty highSo you want a simple explanation of why this is wrong:
"Yes, you can get some green eggs from crossing the F1s.
"If the F1 hen gives the genes for brown, and the F1 rooster gives the gene for blue, you will get some daughters that lay green eggs!"
Basically Single comb is the result of the following traits: p+/p+, r+/r+I'd love to know what else is closely associated with Oocyan and how the straight comb gene plays into the genome. There is a lot more to read!
