Freckles are a dominant trait in humans. Both of these girls have lots of freckles. Their mother has freckles but their father does not. What is the MOST LIKELY genotype that produces the two girls' freckles?

So, lets say that the letter representing freckles is F for dominant or f for recessive
Clearly, the mother is F, while the father is f. which most likely gives the girls the genotype of Ff with one dominant freckle allele each which means they display the trait.

Answer:

FF mom

ff dad

Explanation:

Homozygous is when a chromosome means has two of the same allele, heterozygous is having two different alleles. In order for the girls to have a higher chance to have freckles, the mom must be FF (dominant homozygous) and the father ff (recessive homozygous) since he does not present freckles, doing the Punnet Square:

DAD f DAD f

MOM F Ff Ff

This combination results in a 100% chance the girls will inherit freckles.
