Balancing selection, in contrast to directional selection, maintains genetic polymorphism in populations. For example, if heterozygotes at a locus have higher fitness than homozygotes (a scenario ...

Precisely how lowered levels of the gene product, an enzyme called hexoseaminidase A, protect against TB isn't known. Balanced polymorphism may explain why cystic fibrosis is so common- the ...

investigated polymorphisms of the 5-HT transporter-linked promoter region (5-HTTLPR) gene. This gene has a short (S) allele and a long (L) allele; men with the LL genotype are likely to have ...

The part of DNA that determines what protein to produce and when, is called a gene. First established ... called restriction fragment length polymorphism. Because this process was extremely ...

The following is a summary of “FTO and NOS3 genes associated with pediatric obesity: Corações de Ouro Preto study,” published ...

A research team using EST-SSR molecular marker technology reveals vital information on the genetic diversity and structure of nine natural populations of Phoebe bournei, providing a scientific ...
