Nitro's genes and other budgie genetic musings (lj copy)
Nitro is split to lacewing. I know this because he shows opaline, which is a sex-linked mutation. Since he is a boy, he had to get it from both parents, but first some family history. The lacewing gene originated in the line with Gaus who was an opaline lacewing. That means both of his sex chromosomes carried lacewing and and opaline. I will call the chromosome that has both the Gaus chromosome. He passed it to all his offspring, and the daughters were visual opaline lacewings who could pass it to their sons. Opaline also runs in the Phage line by way of Seagrass, who passed it to Peep. Peep and the Gaus girl gave us the Tesla generation, where all the boys carried the Gaus chromosome as well as an opaline on the other chromosome from Peep. Budgie Man from the Tesla generation fathered the Bullet generation who all had normal skyblue mothers. Budgie man would have given opaline to all his offspring, but there was a 505 chance of it being the Gaus chromosome and 50% the other chromosome. Bullet, Pistol, and Magnum showed the Gaus chromosome, and they had a blue sister who got the other one. All the boys of that generation would have to see what they got by breeding. Blue Brother got the luck of the draw with the Gaus chromosome. He was bred to Emma, an opaline spangle. That meant a 50% chance of opalines for both boys and girls, and since he had the Gaus chromosome, all the visually opaline boys will carry lacewing, and the visually opaline girls will be lacewing. Whitey and Nitro have the Gaus Chromosome, since Nitro is opaline and Whitey is lacewing, but Emma the third got the normal chromosome and doesn't carry any sex linked mutations. Nitro got opaline from both parents.
What this means for the future is that if Minion is paired to Whitey or her little sister from clutch two, all their babies will be opaline, and all sons would carry lacewing. It also means that an opaline would be a good match for Blue Brother. That means any visual opalines from that pairing would either be or carry lacewing. Nitro will have a chance of lacewing daughters, and sons that are split.
I've ignored spangle for this post because it is autosomal dominant, and I've been mainly talking about sex linked genes.
The crosspost from Dreamwidth failed, so I'm copying and pasting this. It will put a duplicate when I make another import over there, but I don't care.
edit: I messed up. Nitro would pass opaline to all his offspring. He could pass the one from Emma or the Gaus Chromosome, so it doesn't matter if he's paired to an opaline or a normal. His sons would be like Blue Brother. They would need test breedings to see if lacewing is present.
