For sites free of natural selection and assuming the same mutation rate across chromosomes, what is the expected rank order of neutral heterozygosity these chromosomes? Why?

5. Would you expected similar levels or different levels of heterozygosity for Y-linked vs. mitochondrial DNA for sites free of selection? Explain.

Explanation / Answer

4.
