Unformatted text preview: pecies, the Swainson’s hawk, a single male and female pair up and have a single baby in each year. a. Assuming all else is equal, which species is likely to have the larger Ne and why? b. Which species will lose heterozygosity more quickly and why? 3 5. You are in charge of estimating the mutation rate in an emerging human virus. You are given a very old sample collected in 1950 that contains DNA from that virus as well as a DNA sample of the same virus collected fifty year later, in 2000. You have the complete genome sequences for both samples. The genome size of this virus is 20,000 base pairs. There are 10,000 replication events per year. You find 2,000 single base pair differences between the samples collected in 1950 and 2000. Assume the entire genome is evolving under neutral expectations. a. What is mutation rate on a per-replication and per year basis in the virus (include units)? b. You find a vial that you know was collected prior to 1950, but you do not know the exact year. Assume that...
