Question

Freckles are caused by a dominant allele (F). What would be the possible genotypes of the offspring if the parents' genotypes are Ff and ff?

a) FF and ff
b) Ff and ff
c) Ff
d) Not enough information to determine

Answer 1

The possible genotypes of the offspring if the parents' genotypes are Ff and ff would be FF and ff, Ff and ff, and Ff.

Step-by-step explanation:

The possible genotypes of the offspring if the parents' genotypes are Ff and ff would be:

a) FF and ff

b) Ff and ff

c) Ff

d) Not enough information to determine

In this case, the F allele is dominant and the f allele is recessive. When the parent with genotype Ff (heterozygous) is crossed with the parent with genotype ff (homozygous recessive), there is a 50% chance of getting the offspring with genotype Ff (heterozygous) and a 50% chance of getting the offspring with genotype ff (homozygous recessive).
