Backcrossing - Wikipedia
Backcrossing is a crossing of a hybrid with one of its parents or an individual genetically similar to its parent, to achieve offspring with a genetic identity closer to that of the parent. It is used in horticulture, animal breeding, and production of gene knockout organisms.
Backcross | Hybridization, Inbreeding, Breeding | Britannica
backcross, the mating of a hybrid organism (offspring of genetically unlike parents) with one of its parents or with an organism genetically similar to the parent. The backcross is useful in genetics studies for isolating (separating out) certain characteristics in a related group of animals or plants.
Introduction to Backcross Breeding | Advanced Backcross Breeding …
The backcross method has been used extensively for transferring qualitative characters (characters with clear phenotypes that are easy to identify in cross progeny) such as disease resistance. It is effective in both self and cross pollinated crop species.
Backcrossing, Backcross (BC) Populations, and Backcross …
Nov 14, 2019 · This page provides an explanation and a visual representation of the backcrossing process and backcross populations. Backcross breeding is an effective method to transfer one or a few genes controlling a specific trait from one line into a second—usually elite—breeding line.
Difference Between Test Cross and Backcross
Feb 20, 2017 · The main difference between test cross and the backcross is that test cross is used to discriminate the genotype of an individual which is phenotypically dominant whereas a backcross is used to recover an elite genotype from a parent which bears an elite genotype.
Backcross - Purpose, Applications, Limitations and FAQs - Vedantu
Backcross can be defined as the method of crossing or mating a hybrid offspring with one of its parents or to a genetically identical individual in a trial to create infants which are genetically identical to the parent.
Backcrossing - an overview | ScienceDirect Topics
Backcrossing is a two-generation breeding protocol that starts by generating hybrid F1 mice between two inbred strains (preferably distantly related), one of them carrying the mutation of interest. Then, F1 mice are mated with a member of one …
Chapter 6: Marker Assisted Backcrossing – Molecular Plant Breeding
Backcrossing (BC) describes a plant breeding procedure used to incorporate one or several genes into an adapted or elite variety. The BC method (Fig. 1) is a form of recurrent hybridization by which a superior characteristic is added to an otherwise desirable genetic background.
1.7: Backcrossing - Biology LibreTexts
Backcrossing is used extensively to incorporate alleles for novel traits into elite germplasm for a cultivar development program. The novel alleles may be natural mutations or may be the result of mutagenesis or genetic engineering. The strategy for conducting a backcrossing program is dependent on the type of cultivar being developed.
Backcross Breeding - SpringerLink
Backcross breeding is a widely used method of transferring a desired trait, either natural or engineered, from one plant to the elite background of another. This process is widely used when working with transgenes because transformable maize …
