Would you expected similar levels or different levels of heterozygosity for y-linked vs. mitochondrial dna for sites free of selection? explain. g

I would expect the same levels of heterozygosity. This is because, for y-linked genes, they are only passed down by men through the Y-chromosome. Similarly, mitochondria DNA is only passed down by females through their eggs since sperm does not carry mitochondria during fertilization.  Therefore most of these genes will be hemizygous in the population.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
