reciprocal cross

views updated

reciprocal cross In genetics, one of a pair of crosses in which the two opposite mating types (or sexes) are each coupled with each of two different genotypes and mated with the reciprocal combination, e.g. male of genotype A × female of genotype B (first cross), and male of genotype B × female of genotype A (the reciprocal cross). Such crosses are used to detect sex linkage, maternal inheritance, or cytoplasmic inheritance.
