Question

In a group of rock pocket mice, some individuals have dark fur and others have light fur. In this group, the gene for the fur color trait has two alleles. The allele for dark fur (F) is dominant over the allele for light fur (). This Punnett square shows a cross between two rock pocket mice. F F F FF FF. F FF FF How many boxes represent offspring with dark fur?

Answer 1

All of the offspring in the cross between two rock pocket mice with the genotypes FF and Ff will have dark fur.

Step-by-step explanation:

In a cross between two rock pocket mice with the genotypes FF and Ff, all of the offspring will have dark fur. The dominant allele for dark fur (F) will always be expressed over the recessive allele for light fur (). Therefore, all of the boxes in the Punnett square represent offspring with dark fur.
