What is a genetic cross between one homozygous recessive individual and one of unknown genotype?
A) Self cross
B) Hybrid cross

D) Test cross
E) F1 cross

Question

Quizplus · Accepted Answer

A test cross is the best choice in this scenario, as it involves crossing the unknown genotype with a homozygous recessive individual. This allows for the determination of the unknown genotype by observing the phenotype of the offspring. Self cross and F1 cross involve crossing individuals with known genotypes, while a hybrid cross involves crossing individuals with different genotypes. A dihybrid cross involves crossing individuals that differ in two traits.
