Unformatted text preview: each year. In another species, 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? 3 The Swainson’s hawk will have the larger effective size because in the Galapagos Hawk only one male breeds but all males breed in the Swainson’s hawk. The Galapagos Hawk will lose heterozygosity more quickly than the Swainson’s Hawk given the sensitivity of H to changes in population size (fig. 10.7 in the book). b. Which species will lose heterozygosity more quickly due to over-hunting and why? The Galapagos hawk will lose heterozygosity more quickly than the Swainson’s hawk, given the sensitivity of H to changes in population size (fig. 10.7 in the book). 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 colle...
