Problem
In a type of chicken, (Andalusian fowl), the allele for black feathers is incompletely dominant to the allele for white feathers. The heterozygous has blue feathers. Determine the genotype of the parents of the following crosses, and the phenotypic ratios of their offspring.
Genotype:
i. Black ______X Blue________ Offspring phenotypic ratios:_________
ii: Blue_______X Blue_________ Offspring phenotypic ratios:__________
iii. Blue_______X White______ Offspring phenotypic ratios:________
