Refer to your Figure 2 at update 500 (i.e. the flrxgenotype histogram)arrow_forwardImagine you raise goldfish as a pet dealer. You have over 10,000 fish in one large tank but, due to an electrical problem, 95% of the fish perish one night. The remaining 5% are left to breed and repopulate, passing their genes and traits on to future generations. What type of genetic drift would this be considered?arrow_forward
