Over time, the size of lizards on one of the islands continues to change. You wonder whether these evolutionary changes are due to natural selection or genetic drift. Which of the following are true of both natural selection and genetic drift? I. Leads to a change in gene frequency II. Favors adaptive traits that increase survival or reproduction III. Can occur in small populations?

I. Leads to a change in gene frequency

III. Can occur in small populations

Explanation:

Natural selection increases the frequency of the alleles that impart one or other beneficial genetic traits to the individuals of a population. These individuals should be able to survive better and reproduce more to be favored by natural selection. Genetic drift also changes the allele frequencies of a population. However, genetic drift is random and does not change it according to the survival fitness of individuals. Both natural selection and genetic drifts can change the gene pool of a small population. However, genetic drift is more effective in smaller populations.
