Detailed explanation-1: -If a mutation introduces a new skin color in a lizard population, which factor might determine whether the frequency of the new allele will increase? natural selection.
Detailed explanation-2: -Explanation: If a mutation introduces a new skin color in a lizard population and that mutation makes some lizards more fit for their environment than other lizards then the frequency of the new allele will increase. For example, if a mutation causes some dark skin color which can help some lizards to survive.
Detailed explanation-3: -4. If a mutation introduces a new trait, which factor might determine whether the frequency of the new allele will increase?-if the new trait make the organism more fit (better adapted to its environment; more likely to survive & reproduce) Page 3 5.
Detailed explanation-4: -Natural selection, genetic drift, and gene flow are the mechanisms that cause changes in allele frequencies over time.
Detailed explanation-5: -Genetic drift is change in allele frequencies in a population from generation to generation that occurs due to chance events. To be more exact, genetic drift is change due to “sampling error” in selecting the alleles for the next generation from the gene pool of the current generation.
