Evolution of Populations
Evolution of Populations

... In the 1940’s, Mendel’s work on genetics was “rediscovered” and scientists began to combine the ideas of many branches of biology to develop a modern theory of evolution. When studying evolution today, biologists often focus on a particular population. This evolution of populations is called microe ...

However, as Macdonald (2003) points out, at the current state of knowledge there are relatively few “simple” genetic disorders, that is, disorders that can be traced to a single gene or to several genes, each of which can still cause the disorder. To date, no single gene or set of genes has been ass ...

Quantitative trait locus

A quantitative trait locus (QTL) is a section of DNA (the locus) that correlates with variation in a phenotype (the quantitative trait). The QTL typically is linked to, or contains, the genes that control that phenotype. QTLs are mapped by identifying which molecular markers (such as SNPs or AFLPs) correlate with an observed trait. This is often an early step in identifying and sequencing the actual genes that cause the trait variation.Quantitative traits are phenotypes (characteristics) that vary in degree and can be attributed to polygenic effects, i.e., the product of two or more genes, and their environment.
