Test cross is used to find_____________?
Correct answer: C. Genotype
- A. Trait
- B. Phenotype

Explanation
A test cross mates an individual showing a dominant phenotype with a homozygous recessive individual. The offspring pattern reveals whether the tested parent is homozygous or heterozygous, so the test cross determines genotype. Phenotype is already visible, while ratios are only the resulting observations, not the purpose of the cross.
