The Australian giant burrowing cockroach (Macropanesthia rhinoceros) is the heaviest cockroach in the world. You are the leading expert on the genetics of this species and are working to domesticate them for food production. Your starting population (G0) has a mean body mass of 30 g and variance of 0.674 g2. You select the largest roaches from this population to breed the next generation (G1). The selected breeders have a mean body mass of 32.4 g and a variance of 0.215 g2. If the narrow sense heritability (h2) of body mass in your cockroaches is 0.35, what will be the expected mean body mass of the G1 population? Round your answer to 2 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.
