Reciprocal crosses (正反交) also called mutual crosses. Two hybrid parents are crossed with each other as female and male parents. For example, if A (
) × B (
) is the direct cross, then B () × A () is the reciprocal cross. Direct and reciprocal crosses are relative, not absolute.
Reciprocal cross (正反交), also called mutual cross, refers to, after a certain hybridization, using the previously used female parent as the male parent and the previously used male parent as the female parent for the cross; or the two sets of crosses together are called reciprocal crosses. As Mendel has applied and confirmed, the hybrids produced by these two sets of crosses generally show no difference, but this is not the case in sex‑linked inheritance and cytogenetics.
