Increase gene combination increasing variation in individuals and variability in the population
Evolutionary studies show greater variability improves the ability of a population to adapt to changes in the environment resulting increased chance of survival
Variability in the population further increases if a greater number of alleles are present for each gene.
Recombination of genetic material and increased number of alleles of particular gene increases variability
Mutations play a part in increasing the number of alleles for the trait whereas meiosis and fertilization play a significant role in recombining genetic material.
