0 the fact that something such as an animal or organism can exist in different forms: --
a polymorphism that may have protected ancestral populations from a form of malaria
Compounds that exist in more than one crystalline form are said to exhibit polymorphism.
Instead, neutrality tests produced significantly negative test statistics, reflecting an excess of singleton polymorphisms.
Genetic load in natural populations : is it compatible with the hypothesis that many polymorphisms are maintained by natural selection ?
None of the polymorphisms was shared or fixed between the two chromosomal types.
Testing for these polymorphisms is relatively simple and cheap.
While this obviously means that most polymorphisms are non-lethal, they could still have subtle implications for human health.
Only biallelic polymorphisms (both point mutations and indels) are included.
Contrasting evolutionary forces driving population structure at expressed sequence tag polymorphisms, allozymes and quantitative traits in white spruce.
Accounting for human polymorphisms predicted to affect protein function.
