Inbred plant
In plant breeding, inbred lines are used as stocks for the creation of hybrid lines to make use of the effects of heterosis. Inbreeding in plants also occurs naturally in the form of self-pollination. Inbreeding can significantly influence gene expression which can prevent inbreeding depression. See more Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction, but more commonly refers to the genetic … See more A measure of inbreeding of an individual A is the probability F(A) that both alleles in one locus are derived from the same allele in an ancestor.

WebInbred lines are homozygous, and, therefore, pure-breeding plants which can be maintained by selfing, unless you are using a male sterile or self-incompatibility system. This facilitates perpetual reproduction of the hybrid and consistency of phenotype and performance, as well as a method of proprietary control of the germplasm. WebAug 1, 2014 · Inbred plants are homozygous for all genes on their chromosomes. Conversely, when the gene (s) are different the individual is termed heterozygous. For example, fruit color in tomato is controlled by the action of a single gene. Every tomato has two genes for the fruit color trait, one from each of its parents.
WebInbreeding is defined as the probability of two alleles in an individual being identical by descent, and is normally the result of mating related individuals. The rate of inbreeding is … Webinbreeding definition: 1. a situation in which plants, animals, or people are produced by breeding between closely related…. Learn more.
WebTechnically, inbreeding is defined as the mating of animals more closely related than the average relationship within the breed or population concerned. Matings between animals less closely related than this, then, would constitute outbreeding. These two systems of mating, with varying intensities in each, are described in Table 1.
WebAn inbred line is a pure line, or nearly homozygous line, usually developed by inbreeding. The source of the inbreds may be an open-pollinated variety; a single, three-way-, or double-cross hybrid; a synthetic variety; or a population improved through recurrent selection.
