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

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
