The purpose of performing a test cross is to: A. Determine the genotype of a plant at F 2 B. Predict whether two traits are linked C. Assess the number of alleles of a gene D. Determine whether two species or varieties will breed successfully
Option A A test cross is an experiment that is used to find out the genotype of a dominant plant of the F2 generation. It is performed by crossing the dominant offspring with the homozygous recessive parent. A tall plant (unknown genotype) is crossed with a dwarf plant (known genotype).
