In some chicken the gene for feather color is controlled by codominance.the allele for black is B and the allele for white is W. The heterozygous phenotype is known as erminette.
A.what is the genotype of black chickens?

2.If two erminette chickens were crossed what is the probable phenotype of an off spring?

Answer:
A. BB. EXPLANATION : The colour black in a chicken is expressed by the allele B. The color white allele is expressed as W similarly.
B.If the "feather color allele" on both chromosomes carries the gene for white feathers (n), the chicken will have the genotype (n,n) and will be phenotypically white.
C.In some chickens, the gene for feather color is controlled by codominance. The allele for black feathers is B and white feathers is W. The heterogenous genotype is known as erminette.
2. both alleles are expressed and the phenotype is a mixture or patches ... If two erminette chickens were crossed, what is the probability that:
