... (b) human chromosome 1 (1q23). The Slam gene family exhibits considerable gene-number and gene-position homology between the murine and human genomes, contrasted with the Ifi and Fc R gene families, which show considerable diversity in both gene number and gene position. These latter gene families hi ...

... (alleles), and that each of the organism’s gametes contains one and only one of these factors. In this way, the alleles segregate during meiosis, providing for genetic variability among the organism’s offspring. This is apparent in monohybrid crosses—matings involving only one trait. Mendel’s Law of ...

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.
