Look at the result of the Punnett square. This is brought about by the presence of the Muff Beard gene Mb. One would normally write: (F, F) crossed with (f+, f+) gives (F, f+) times 4.So, in order to get the four combinations of the genes of the two parents, just take the first gene of the first pair with each gene of the second pair, then do the same thing with the second gene of the first pair. I think it also depends which colour you use to get the lav, for example birds that have been bred to black birds will be split for E or ER depending upon the genetics of the black bird. If you began by using a homozygous blue laying breed, around 75% of the F2 chicks will inherit at least one blue egg gene and should lay a shade of olive.
