Question

Mutations can change allele proportions. The new allele frequency was 0.0 but is now >0.0. 1) Keep the evolutionary parameters all at 0 except for the ‘Mutation rate', change this to 0.01 for R the 'Initial ‘R'Allele Proportion' to 0.5. Let the experiment run for –500 generations and record yo results. Q3. Use your results to explain the effect of mutation on the allele frequencies in the populatio time. 197 Population Size Generations 501 Population Size Proportion R allele 0.26 Proportion rallele 0.74 Prop. ir Genotype 0.54 Prop.

Answer 1

The allele frequency at first is decreasing but due to the mutation rate, the allele frequency is gradually increasing thereby fixing the allele in the population. This helps in increasing the R allele frequency in the population.
