Natural selection favors advantageous alleles leading to increased genetic variation in populations.
Natural selection leads to an increase in genetic variation in a population by favoring certain alleles that provide advantages for survival and reproduction. For example, if an allele confers a phenotype that allows individuals to better adapt to their environment, those individuals are more likely to survive and pass on their advantageous alleles to the next generation, increasing genetic diversity.
Mutation rate influences the outcome of the Luria-Delbrück experiment by introducing new genetic variations. Higher mutation rates can lead to a broader range of genotypes, impacting the diversity of traits within a population.
Increasing the mutation rate introduces new variations into the population, potentially leading to novel traits and adaptations that can enhance a species' genetic diversity and ability to thrive in changing environments.
