Lecture 11 - Population Evolution

Question 1

how does linkage disequilibrium affect HWE

Answer 1

it affects how quickly HWE is reached

Question 2

types of mutation

Answer 2

insertion, deletion, substitution, rearrangement, inversions

Question 3

effects of mutations

Answer 3

silence mutation, misuse mutation, nonsense mutation

Question 4

linkage disequilibrium

Answer 4

non random association of loci

Question 5

undesirable mutations

Answer 5

mutations that are harmful or lethal to an individual can accumulate in a population

Question 6

where do undesirable mutations hide

Answer 6

in heterozygotes

Question 7

why are undesirable mutations less common in self-pollinating species

Answer 7

the # of heterozygotes is reduced when inbred, so there is less of a chance for the mutation to hid

Question 8

what type of population is more susceptible to migration

Answer 8

outcrossing species, as it is more likely to cross with something else

Question 9

factors that could influence the rate of migration

Answer 9

enforced/encouraged outcross
distance
environment
population size

Question 10

is mutation or migration a bigger evolutionary force

Answer 10

migration

Question 11

is mutation rates faster or slower than migration rates

Answer 11

slower
