1). Penguins in Stewart Island have a recessive mutation "twist-tail" that causes problems in the control of direction when swimming. In 2008 a survey of a large, freely interbreeding, population of 2,732 penguins revealed 316 with twist-tail phenotype. a) What percentage of the penguin population would you expect to be heterozygous at the twist-tail locus ? b) Where there is no mutation, migration or selection what percentage of the next generation would be homozygous dominants, heterozygotes and homozygous recessives?

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.
