Concept:A genetic cross shows the alleles of each parent; homozygous means two identical alleles, whereas heterozygous means two different alleles.
Explanation:In the diagram, the male parent has the genotype
Tt because it carries both
T and
t alleles.
So the male is heterozygous, not homozygous.
The female parent has the genotype
tt, carrying two identical recessive alleles.
Therefore, the female is homozygous.
This makes option C the correct statement about the cross.
Answer:C. The female is homozygous
