Question
**Question:** Choose the answer below that is true of gene flow. **Options:** - ○ all of these - ○ none of these - ○ gene flow makes populations more similar - ○ gene flow may introduce new alleles into a population - ○ gene flow almost certainly alters allele frequencies **Explanation:** Gene flow refers to the transfer of genetic variation from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and can be considered a single population. This process can have significant effects on the genetic diversity of populations: 1. **Gene flow makes populations more similar:** It can reduce the genetic differences between populations by mixing alleles, often making them more genetically similar. 2. **Gene flow may introduce new alleles into a population:** The introduction of new individuals into a population can result in new alleles being introduced, increasing the genetic variability. 3. **Gene flow almost certainly alters allele frequencies:** By introducing or removing alleles, gene flow can change the frequencies of those alleles within a population. The correct answer is "all of these," emphasizing that all the statements provided about gene flow are true.
