onsider selection on two traits. The selection gradient on trait 1 is -0.2, and the selection gradient on trait 2 is 0.25. The additive genetic variance of traits 1 and 2 is 0.53 and 0.42, respectively, and they have a genetic covariance of 0.2. Round all answers to 3 decimal places.
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.
Question:-
Consider selection on two traits. The selection gradient on trait 1 is -0.2, and the selection gradient on trait 2 is 0.25. The additive genetic variance of traits 1 and 2 is 0.53 and 0.42, respectively, and they have a genetic covariance of 0.2. Round all answers to 3 decimal places.
a) What will be the predicted evolution response of each trait?
b) What would the predicted evolutionary response be if the covariance was 0?
c) How does the genetic covariance between the traits influence evolution?
