Solution

The correct option is D Test cross
A test cross is performed to determine the genotype of an offspring that is , if it is a heterozygous- or homozygous-dominant. For the purpose, the offspring is crossed with a homozygous recessive parent. Back cross is a cross between $F_{1}$ hybrid and one of the parents to deduce the genotype of both parents and the hybrid. Outcross refers to breeding between two distantly related organisms. The correct answer is option B.
