To determine the likelihood of the autosomal dominant trait being passed on from the given genotypes of the parents, we can set up a Punnett square.
The father is homozygous recessive (genotype xx), and the mother is heterozygous (genotype Xx).
Here is how the Punnett square would look:
X x
----------------
x | Xx | xx |
----------------
x | Xx | xx |
----------------
From this Punnett square, we can see that:
- Two out of the four boxes (50%) will be Xx (inheriting the dominant trait).
- Two out of the four boxes (50%) will be xx (inheriting the recessive trait).
So the correct answer is:
50% Xx; 50% xx.
