The so-called "blue" (really a characol gray). Andalusian chicken is produced by a cross between the black and white varities. Only a single pair of alleles is involved. What color chickens (and in what proportions) would you expect if you crossed two blues? If you crossed a blue and a black? explain.

Do your punnet square(s). It is easy. one set of alleles.

sairakhan19, if the problem says that the Andalusian chicken (blue variety) is produced by a cross between the white variety and the black variety and that only a single pair of alleles is involved, don't you think that it could be a case of intermediate heredity?

AA - White
BB - Black
AB - Blue

Now, as canalon says, do the Punnet squares. They are very simple (there is only a set of two alleles).

I hope I've solved your doubt...

the "blue" chicken is a result of incomplete dominance...so the the heterozygote is a intermediate phenotype between the homozygous dominant and the homozygous recessive

blue= Aa
simple mendelian cross
