Question

Black fur (A) is codominant with white fur (a) and brown eyes (B) are dominant to blue eyes (b) in mice. Two mice are heterozygous for both traits. If these mice are crossed, what color of fur will the offspring with genotype Aa express? Justify your answer​

Answer 1

Answer :-

Co-Dominance is the phenomenon in which no allele is dominant over each other and express themselves independently when present in an organism.

Here, Black fur is codominant with white fur i.e. neither of the trait is dominant over each other. So, the colour of the offspring having both traits can't be black or white as neither of the traits are dominant.

Colour of the fur of the offspring with genotype Aa will be white and black spotted.
