At the time, the rat gene map was quite limited and contained approximately 70 loci that were associated in ...

Linkage and Recombination

... The frequency of intragenic recombination is usually low so it can only be detected by selecting recombinants from large numbers of progeny. Rosy gene is about 0.005 cM long, i.e. recombination between markers at the ends of the gene occurs in about 0.005% or 0.00005 = 5 X 10-5 of all gametes from a ...

... This simply means that several marker loci, which are known from other studies to be close to each other, are simultaneously checked for linkage with the disease in question. If there is true linkage, all markers adjacent to the disease locus are expected to be linked. The combination of alleles tha ...

When multilocus haplotypes are of interest, there is often an additional assumption of Hardy-Weinberg equilibrium (HWE). Here I describe a g ...

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.
