I’ve been working the Punnet squares for the F2s and my brain is spinning. :th
I think I’ve gotten all of the potential outcomes/genotypes. I’m at 32(?) potential outcomes?
This is why I like to work with one single gene. A Splash rooster over black hens equals all blue chicks! :cool: Easy...
Yes. Split means they carry it and do not physically show that they have the gene.
I personally don’t care much for the “split” terminology, but it’s what most people use.
Oh! Yes, males will only be single factored barred since the original females are only single barred.
Double factored barred males have two barring genes (BB...is B the right shorthand code?) and so the bars are very obvious and lighten the whole bird. Think Barred Rock roosters versus the...
Aw! Thanks. I’ll try to keep it simple.
In general, in sex-linked crosses, the hens determine the patterning of the male. Z and W are the sex chromosomes, with Z being the most important and holding genes while the W doesn’t do much but tell the body to produce female hormones/organs.
ZZ - male...
Since the silver duckwing rooster is SS (silver) he’ll always pass on an silver gene, and it’ll go to every offspring male or female. The hens, since they are gold (wildtype), are s+ which is located on the Z chromosome. Roosters are ZZ, hens are ZW, so the pattern can only be passed onto the...
Okay was eating dinner, time to read!
Hmm. The flowery hens are single barred, and mottled I think? (I don’t know the common names for the the patterns sorry). Would they be gold patterned or golden?
Silver duck wing is silver patterned black and that’s all I know for that lol.
