In populations where it is common for first cousins to marry, some autosomal recessive disorders such as albinism and phenylketonuria are far more likely to occur than elsewhere. 20. If the frequency of a recessive allele changes from 0.0001 to 0.01 after several generations, the most probable reason is that random mating is occurring non-random mating is occurring a high rate of mutation is involved inbreeding causes the population to increase

Genetic Variation

Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.

Quantitative Genetics

Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
