Katyanochek1 [597]

Answer:

4 types of phenotypes with phenotypic ratio 9:3:3:1 will be obtained.

Explanation:

The Punnett square diagram for the cross between mice with genotype BbCc & BbCc is attached.

It is clear from the diagram attached that the phenotypic ratio will be 9:3:3:1

The following 9 genotypes will show dominant trait for both the characters i.e. characters represented by B & C genes.

BBCC, BBCc, BbCC, BbCc, BBCc, BbCc, BbCC, BbCc, BbCc

The following 3 genotypes will show dominant trait for one character represented by gene B and recessive trait for other character represented by gene C.

BBcc, Bbcc, Bbcc

The following 3 genotypes will show recessive trait for one character represented by gene B and dominant trait for other character represented by gene C.

bbCC, bbCc, bbCc

The following genotype is the only genotype which will show recessive trait for both the characters represented by gene B & C.
