In order for speciation to occur, there has to be a reduction in Gene Flow Genetic Drift Mutation Selection

Reproductive isolation leads to induced mutations emergence of separate species immunity to genetic drift high rates of gene flow

40. Which of the following microevolutionary forces act upon existing variation within a breeding population?   gene flow and natural selection   natural selection and genetic drift   gene flow and mutation   genetic drift , gene flow, and mutation   natural selection, mutation, genetic drift, and gene flow

I need help with a biology question: Sometimes a restriction in genetic variability is imposed on populations by natural catastrophes such as flooding, earthquake, etc. The surviving individuals reflect only a small, random genetic sample of the population affected. This process is termed    sudden mutation the founder effect non random mating gene flow

Which of the following are factors that can impact genetic variation in a population? (Select all that apply.) Lack of natural selection Random mating Mutation | Migration

If a goose with genotype Aa had migrated instead of the goose with genotype aa, would the scenario still be considered gene flow? Why or why not?

What force, which changes gene frequencies, occurs if there is a failure to reproduce or if individuals become isolated from the rest of their population?         mutation         radiation         genetic drift         nonrandom mating
