TABLE 1 Data for Bean Simulation for F1 and F2 Generations: F1 Generation Observed Frequency of Observed frequency of alleles GENOTYPES TOTALS Genotypes = proportion out of 50 BLACK, BLACK (AA) A= 12 BLACK, WHITE (Aa) 19 a= WHITE, WHITE (aa) 19 F2 Generation BLACK, BLACK (AA) A= 14 BLACK, WHITE (Aa) 24 WHITE, WHITE (aa) 12 6. To calculate expected frequencies in the F1 generation, use the original allelic frequencies A = 0.40 and a = 0.60. Remember that the frequency of A = p and the frequency of a = q. Expected A = Expected a = 7. Calculate the expected genotypic frequencies in the F1 generation using the Hardy-Weinberg equation: p2+2pq+q2 = 1
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.
