A common test to find the genotype of a hybrid is by:

A $crossing of one F_{2} progeny with male parent$
B $crossing of one F_{2} progeny with female parent$
C $studying the sexual behaviour of F_{1} progenies$
D $crossing of one F_{1} progeny with recessive parent$

Solution & Step-by-step Explanation

A test cross is used to determine the genotype of an individual showing a dominant phenotype. It involves crossing the unknown individual (usually an F_{1} hybrid) with a homozygous recessive parent. If any offspring show the recessive trait, the unknown was heterozygous.
