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.
- If instead of 40 cM the two gene loci are 30 cM apart and an AAbb and aaBB individual mate:
- What gametes will the F1 individuals produce and in what frequencies?
- What
phenotype classes and in what frequencies are expected in the F2 generation Note:Assume complete dominance for both genes.
