In some chickens, the gene for feather color is controlled by codominance. The allele for black feathers is B and the allele for white feathers is W. The heterozygous phenotype (physical trait or color that results from these two parents) is called erminette.What is the genotype for chickens with black feathers?A) BbB) BBC) WWD) WB

Respuesta :

Answer:

B) BB

Explanation:

The gene for feather color is controlled by codominance ( codominance, when both the alleles express their effect, the phenotype is the combination of both alleles, it is the intermediate of both phenotypes).

black feathers is B

erminette feathers WB

white feathers is W

Then the genotype for chickens with black feathers is  BB.

also the Bb may be black this is heterozygous condition.
