Freckles are a dominant trait in humans. both of the girls have the genotype ff for freckles. if either one marries a man with no freckles, what are the chances that their children will have freckles? a) 0% b) 50% c) 75% d) 100%

The correct answer is option D, 100 %

Explanation:

Freckles are a dominant trait in humans

The female partner has genotype = FF

The male partner with no freckles shall have genotype = ff

The cross between the above two is represented through a punnet square-  

FF

f FfFf

f FfFf

Thus all the offspring will have genotype Ff,  

Since the dominant allele is F . thus all the offspring would have freckles
