Genetic correlation — refers to the proportion of variance that two traits share due to genetic causes. Outside the theoretical boundary case of traits with zero heritability, the genetic correlation of traits is independent of their heritability: i.e., two traits can … Wikipedia
Genetic determinism — is the belief that genes determine physical and behavioral phenotypes. The term may be applied to the mapping of a single gene to a single phenotype or to the belief that most or all phenotypes are determined mostly or exclusively by genes. While … Wikipedia
Genetic association — is the occurrence, more often than can be readily explained by chance, of two or more traits in a population of individuals, of which at least one trait is known to be genetic. Studies of genetic association aim to test whether single locus… … Wikipedia

Genetic diversity — is a level of biodiversity that refers to the total number of genetic characteristics in the genetic makeup of a species. It is distinguished from genetic variability, which describes the tendency of genetic characteristics to vary.The academic… … Wikipedia
Genetic distance — refers to the genetic divergence between species or between populations within a species. It is measured by a variety of parameters. Smaller genetic distances indicate a close genetic relationship whereas large genetic distances indicate a more… … Wikipedia
