What Does This Figure Tell Us About Diversification and Effective

question 39

Multiple Choice

What does this figure tell us about diversification and effective population size in the Y chromosome and mtDNA?

• A) Y chromosome diversity and effective population size decreased dramatically during the migration out of Africa, followed by a significant increase in effective population size. mtDNA diversity and effective population size dramatically increased and is significantly larger than that of the Y chromosome.
• B) Y chromosome diversity and effective population size increased dramatically during the migration out of Africa, followed by a severe restriction in effective population size. mtDNA diversity and effective population size dramatically increased and is significantly larger than that of the Y chromosome.
• C) Both diversity and effective population size increased steadily and significantly for the Y chromosome and mtDNA during the migration out of Africa and are now approximately equivalent to each other.
• D) Y chromosome diversity and effective population size decreased during the migration out of Africa and then recovered to become approximately equivalent to mtDNA.
