A test cross is pretty important in genetics as it helps you determine an unknown genotype. In a test cross, a homozygous recessive(both alleles are identical) individual is crossed with an individual with unknown genotype, exhibiting a dominant phenotype. read more
Calculation of Three Point Test Cross: The recombination percentage or unit distance between genes is worked out by calculating the crossing over percentage between different genes. Suppose number of crossover progeny between genes A and B is P, between genes B and C is Q, between genes A and C is R, and total progeny is T. read more
In genetics, a test cross, first introduced by Gregor Mendel, involves the breeding of an individual with a phenotypically recessive individual, in order to determine the zygosity of the former by analyzing proportions of offspring phenotypes. read more
