Which term describes the example below? a child with no freckles has a mother who has freckles and is heterozygous and a father who has no freckles and is homozygous recessive. a. homozygous dominant b. homozygous recessive c. heterozygous d. female e. male

It is C as to have freckles you have to have a dominant and recessive gene (can be worked out using a punnett square) as the child has 50% of not having freckles like his dad or 50% having freckles like his mom. 
                     male genes(homozygous recessive)
                     f            f

female    F    Ff           Ff
genes
              f     ff             ff

so ff is not having freckles and being homozygous recessive, or Ff having freckles and being heterozygous.

So the child is heterozygous  so C
