Erminette chickens (bw) display codominance. black is dominance. white is dominant. erminette chickens are speckled with black and white feathers. what is the phenotypic ratio of the offspring if two erminette chickens are crossed?

1 BB: 2BW: 1WW

Explanation:

The probability of getting a black chicken is 1/4, that of black-white is 1/2 and that of a white chicken is 1/4. In codominance, there is intermediate expression in the phenotype.

       B                W

B    BB              BW

W   BW             WW

The phenotypic ratio is 1 black: 2 black-white: 1 white

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

the answer is sex-linked recessive.
