... Genetic diseases are defined as diseases caused by aberrations of genetic material. Therefore, these diseases can potentially be passed from generation to generation. However, not every patient has a family history of a similar problem. This is because new mutations can occur when an individual inhe ...

Genetic Inheritance Type Review

... Some traits have more than two alleles and thus have unique inheritance patterns. For example, human blood type is controlled by three alleles (A, B, O). O is recessive and A and B are co-dominant. A person must receive two O alleles for them to have type O blood. If a person receives an A allele an ...

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.
