Explanation: Closely related species have few differences, so you need a fast-evolving region (like mtDNA) to see variation. Slow-evolving genes (like rRNA) are used for distantly related species.
If the recombination frequency between Gene A and Gene B is 10%, and between B and C is 5%, Gene B sits between them if the distance from A to C is 15%. 4. Natural Selection and Genetic Drift introduction to genetics and evolution coursera quiz answers
