Inbred plant
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. WebAn inbred is a pure-breeding strain of corn. This means that if an inbred is self-pollinated, all of the progeny will be genetically identical to each other and to the inbred parent. This process of repeated self-pollinations is …

WebInbreeding is producing seed by selfing over 5–7 generations to develop plants that are highly homozygous at most loci in their genomes. Homozygosity results in identical … WebInbreds usually are produced by continuous generations of self-pollination. If an individual plant is heterozygous at a locus, approximately seven generations of self-pollination are …
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 … 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.

Except in certain rare circumstances, such as new mutations or uniparental disomy, both parents of an individual with such … See more Effects Inbreeding increases homozygosity, which can increase the chances of the expression of deleterious or beneficial recessive alleles and therefore has the potential to either decrease or increase the fitness of the … See more
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 … WebHybrid seeds are used to improve the characteristics of the resulting plants, such as better yield, greater uniformity, improved color, disease resistance. An important factor is the heterosis or combining ability of the parent plants. Crossing any particular pair of inbred strains may or may not result in superior offspring.

WebInbreeding is also used to reveal deleterious recessive alleles, which can then be eliminated through assortative breeding or through culling.
