Ambiguity aversion and familiarity bias

... A gene is the basic unit of heredity in a living organism. The gene concept is an empirical construct preceding the molecular biology era and based on breeding experiments in plants (first by Gregor Mendel in 1866) and animals. At the beginning of the 20th century Mendel’s genes were identified with ...

To date, the genetics underlying idiopathic curvature have not been identified. This is most likely a consequence of several factors, including inconsistent pedigree const ...

The usual formulation is in terms of random genetic drift; however, the problem I want to address concerns fur length, which is a phenotype. To decide how random genetic drift would influence the evolution of this phenotype, we’d ha ...

Any individual haploid strain of yeast may have zero, one, (1949) and or several SUC+ alleles; for example, the early studies oi GILLILAND WINGEand ROBERTS(1952) showed that S. chevalieri possesses three SUC+ genes, but S. italicus has none. Thus, both the number of SUC+ alleles in the genome ...

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.
