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.
Compute for the gene and genotype frequencies of the progeny at each generation (0 to 3). Take note that
the process of drawing two pairs of buttons for 50 times and taking note of the genotypes of the mating types
were repeated when the computed f(A) > 0.60 and/or f(a) < 0.40. This is to ensure that the process was
executed randomly. (see attached table 1)
