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
D is probably right cos you are comparing data
A scientific experiment, in the form of the scientific model, is a testable model used to seek explanation for natural phenomena.
Bacteria! Bacteria! Bacteria! :)
