Answer 2

The genotype for a black chicken is BB.

EXPLANATION :

• The colour black in a chicken is expressed by the allele B. The color white allele is expressed as W similarly.
• If the genotype is homozygous and BB then the colour of the chicken would be black.
• Similarly, if the chicken has homozygous genotype WW then the color of the chicken would be white.
• If the chicken will have hetrozygous genotype BW then the color of the chicken will be Erminette.
