Population genetics

incidental selection of non-harmful genes which are close to a beneficial gene on the same DNA chain

description of how a trait or gene changes in frequency over time

biological selection in which heterozygotes are fitter than homozygotes for either allele

In zoology, intergradation is the way in which two distinct subspecies are connected via areas where populations are found that have the characteristics of both. There are two types of intergradation: primary and secondary.

thumb|300px|This Leucism|leucistic Indian peacock, Pavo cristatus, is unlikely to find a mate and reproduce in a natural setting due to its unusual coloration. However, its striking colour is appreciated by humans, and may be included in artificial [[selective breeding to produce more individuals with the leucistic phenotype.]]

Notch homolog 2 N-terminal-like is a family of proteins that in humans consists of 3 proteins (NOTCH2NLA, NOTCH2NLB, and NOTCH2NLC) and is encoded by NOTCH2NL gene. It appears to play a key role in the development of the prefrontal cortex, a part of the brain.
