Roo-turken, Hen-EE? Resulting Pullet=green eggs? Need genetics help!

Not if you cross them with a Single Comb bird..

you have about 3% of the O gene to cross over...

I am not sure what you mean here - how can only 3% of the O gene cross over from an OO parent? .

the O gene is Linked to the P gene by 5 Maps Unit, what does this mean? it means they can not segregate independently, it means there is 95 to 98% chance the the Only Pair of the O gene will go where the P gene will go..

what can alter this? gene cross over, if by chance(less than 5%) the O gene crosses over to the p+(single Comb) it will stay with the p+ gene.. what does this mean, it is HIGHLY(not imposible) unlikely that in a mating of O/o x o/o the O/o hen will have a single comb.. But it happens, but it is extremely rare, just check the Famus LegBar, they are single comb yet they lay colored eggs...

that is expected as ALL boys and girls will be O/o...

Quote:
see above reference on the linkage of P and O..

Quote:
all that prooves is that the EE are O/o ...

I see.....

I think......you are talking comb and egg color crossing each other. The blue egg gene attaching to the single comb gene - O attaching to p instead of staying with P. So you would have a bird who was Oo and pp (or is it p+p+?) - a blue/green egg layer who was single combed.



I am just talking egg color - regardless of comb type - all OO birds crossed with oo birds will lay Oo eggs.

Correct and the odds of that are less than 5%...

but it happens some times, just check the Legbar...

True.. but 95% of the time they will be Heterozygous for Pea Comb(P/p+) where p+ is recessive to P
