Another scheme, incomplete dominance, is used by many plant and animal alleles for resolving heterozygous loci, particularly in traits that have more than two simple v ...

The Y chromosome is much smaller than the X, so it is missing many genes. This means many genes on the X chromosome do not ...

... From this experiment Mendel was able to conclude that there are at least two factors that control each trait. We now know these factors are genes and that they are located on chromosomes. Genes exist in alternate forms called alleles. Each of Mendel’s pea plants had two alleles of the gene that dete ...

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.
