For example, the human major histocompatibility complex (MHC) region is a complex of tightly linked genes all acting in the immune system, but has no claim to be a supergene, even though the component genes very likely have epistatic effects and are in strong disequilibrium due in part to selection.
Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction.Two genetic markers that are physically near to each other are unlikely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be more linked than markers that are far apart.
The simplest model of meiotic drive involves two tightly linked loci: a Killer locus and a Target locus. The segregation distorter set is composed by the allele Killer (in the Killer locus) and the allele Resistant (in the Target locus), while its rival set is composed by the alleles Non-killer and Non-resistant. So, the segregation distorter ...
As phratries were tightly linked to eligibility for citizenship and participation in the duties of citizenship, it is thought that they declined as a result. Another related and complementary theory is that citizenship became more tightly linked to military service rather than descent, which had a similar effect on the phratries and their ...
Marker assisted selection or marker aided selection (MAS) is an indirect selection process where a trait of interest is selected based on a marker (morphological, biochemical or DNA/RNA variation) linked to a trait of interest (e.g. productivity, disease resistance, abiotic stress tolerance, and quality), rather than on the trait itself.
Eleven forms of loose coupling and their tight coupling counterparts are listed in: [4] physical connections via mediator, asynchronous communication style, simple common types only in data model, weak type system, data-centric and self-contained messages, distributed control of process logic, dynamic binding (of service consumers and providers),
At the same time, it's important to remember that your pup doesn't know what day it is, so it's NBD if the budget is tight this year. Take it from Marshmallow—dogs will be just as happy to spend ...
Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
