Gray tree frog (Hyla versicolor) males call to females, and their calls can be characterized by the pulse number and call period. The additive genetic variance of pulse number is 0.37, the additive genetic variance of call period is 0.16, and the covariance of the two traits is 0.25. What is the additive genetic correlation of the two traits?
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.

the pulse number and call period. The additive genetic variance of pulse number is 0.37,
the additive genetic variance of call period is 0.16, and the covariance of the two traits is
0.25. What is the additive genetic correlation of the two traits?
Additive genetic variance is a component of the total genetic variance in a population that arises from the additive effects of alleles at different loci. This variance is associated with the combined influence of multiple genes, each contributing independently to a particular trait or characteristic. Additive genetic variance is an important concept in quantitative genetics.
