Hybridization is a basic property of nucleotide sequences and is taken advantage of in numerous molecular biology techniques. Overall, genetic relatedness of two species can be determined by hybridizing segments of their DNA (DNA-DNA hybridization). Due to sequence similarity between closely related organisms, higher temperatures are required ...
A mule is a sterile hybrid of a male donkey and a female horse.Mules are smaller than horses but stronger than donkeys, making them useful as pack animals.. In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction.
In genomics, DNA–DNA hybridization is a molecular biology technique that measures the degree of genetic similarity between DNA sequences. It is used to determine the genetic distance between two organisms and has been used extensively in phylogeny and taxonomy .
Introgressive hybridization - hybridization resulting in the transfer of a gene or genetic tract from one species into the gene pool of another species by repeated backcrossing. Intrinsic incompatibilities - environment-independent reproductive barriers.
Introgression, also known as introgressive hybridization, in genetics is the transfer of genetic material from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species. Introgression is a long-term process, even when artificial; it may take many hybrid generations before ...
Hybridization without change in chromosome number is called homoploid hybrid speciation. [1] This is the situation found in most animal hybrids. For a hybrid to be viable, the chromosomes of the two organisms will have to be very similar, i.e., the parent species must be closely related, or else the difference in chromosome arrangement will ...
The identification of these chromosomal abnormalities has led to the discovery of a very large number of "cancer genes" (or oncogenes). The increasing knowledge of these cancer genes now allows the development of targeted therapies, which transforms the prospects of patient survival. Thus, cytogenetics has had and continues to have an essential ...
Introgression is gene transfer among taxa and is a result of hybridization, followed by repeated backcrossing with parental individuals. Introgressive hybridization occurs often in plants, and results in increased genetic variation, which can facilitate rapid response to climate change. [3]
