Zoology - Principles of Inheritance and Variation Question with Solution | TestHub

In Genetics, a test cross, first introduced by Gregor Mendel, is used to determine if an individual exhibiting a dominant trait is homozygous or heterozygous for that trait. More simply, test cross determines the genotype of an individual with a dominant phenotype. In some sources, the test cross is defined as being a type of back cross between the recessive homozygote and ${\mathrm{F}}_1$ generation.
