Test cross

In genetics, a test cross was first introduced by Mendel in order to determine if an individual exhibiting a dominant trait is a homozygous dominant or a heterozygous dominant. To do this, he crossed the a homozygous recessive individual. If all offspring display the dominant phenotype, the individual in question is homozygous dominant; if the offspring are split equally between the dominant and recessive phenotype, the individual is heterozygous.

Test Cross crosses a homozygous recessive with an individual with an unknown genotype. If all the offspring are dominant phenotype, the individual is Homozygous Dominant. If the offspring are half dominant and half recessive, the individual is Heterozygous.
