backcrossing

Purposeful introgression is a long-term process; it may take many hybrid generations before the backcrossing occurs.

It is thought to have arisen from a backcrossing of the F1 hybrid with S. vulgaris.

This has enabled him to propose a creative methodology for producing wheat substitution lines through nullisomic backcrossing.

Selection Theory for Marker-assisted Backcrossing.

Subsequent backcrossing and isolation of opposite mating type strains for the some of the mutants allowed definition of an additional complementation group.

In backcross conversion, genes are introgressed from a donor cultivar or related species into a recipient elite line through repeated backcrossing.

Backcrossing of many generations of the hybrid Bekisar males with feral domestic game hens must occur before fertile females are produced.

The only possible interpretation was that these phenotypes were in fact due to 129 alleles that were replaced by B6 alleles with further backcrossing.

Marker-assisted backcrossing (MABC)

Backcrossing may be deliberately employed in animals to transfer a desirable trait in an animal of inferior genetic background to an animal of preferable genetic background.

Backcrossing is a crossing of a hybrid with one of its parents or an individual genetically similar to its parent, in order to achieve offspring with a genetic identity which is closer to that of the parent.

Introgression, also known as introgressive hybridization, in genetics (particularly plant genetics) is the movement of a gene (gene flow) from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species.
