Mating of a two-breed crossbred offspring back to one of its parental breeds.

A mating between an F1 or F1' individual to one of its parents (P1 or P2) or to another individual that is genetically identical to one of its parents. The term "backcross" may be used [..]

Crossing a hybrid offspring back to either parent. bacteria

A cross between a hybrid individual and one of the parental genotypes

  Cross of a hybrid (F1) mouse to one of its homozygous parents. Also the cross of an F1 heterozygote with a partner that has the same genotype as one of its parents (when working with non-inbred syst [..]

A backcross is a hybrid plant that has been bred with one of its parents (or a plant that is genetically similar) in order to create offspring that is closer to that of the the original parent. For ex [..]

(v) mate a hybrid of the first generation with one of its parents

the offspring of a hybrid crossed with one or the other of its parents; in the case of interspecific hybrids, with a member of one or the other parent species.

The cross of an individual with one of its parents or an organism with the same genotype as a parent.

Crossing a hybrid back to one of the original parents, called the recurrent parent. In agronomy, the recurrent parent is usually a single genotype, often a named variety. In forestry, the recurrent parent is usually a different genotype from the same species or population. (This is done to prevent inbreeding depression.) Example: collecting pollen [..]

A type of genetic cross in which a hybrid strain is crossed to one of the two parental strains.
