3. One similarity between natural selection and genetic drift is that both events (1 point)are based completely on chance. begin with one or more mutations. involve a change in a population's allele frequencies. take place only in very small groups.
Weegy: One similarity between natural selection and genetic drift is that both events involve a change in a population's allele frequencies. User: 4. A farmer sprays insecticide on his crops to kill unwanted insects. Most of the insects die, and the chemicals have the effect of damaging the DNA of the insects that are not killed. Which of these has happened? (1 point)Sexual selection among the insects has changed the gene pool. Genetic equilibrium has been maintained. Mutations have arisen that may have altered allele frequencies. Individuals with new genes have immigrated into the population. Weegy: Mutations have arisen that may have altered allele frequencies. User: 5. Genetic drift tends to occur in populations that (1 point)are very large. are small. are formed from new species. have unchanging allele frequencies Weegy: Genetic drift tends to occur in populations that are small. -Genetic drift is more likely to be significant in small [ populations ] (More)
