7.2 evolution

Question 1

hardy weinberg equation

Answer 1

p^2+2pq+q^2

Question 2

p+q=

Answer 2

1

Question 3

what does p^2 stand for

Answer 3

homo dom

Question 4

what does q^2 stand for

Answer 4

homo rec

Question 5

what does hardy weinberg/micro evolution study

Answer 5

if populations are evolving based on allelic frequency

Question 6

sources of genetic variation

Answer 6

1. point mutations
2. chromosomal mutations
3. sexual recombination ( contributes most)

Question 7

conditions for hardy weinberg

Answer 7

1. no mutations
2. random mating
3. no natural selection
4. large pop size
5. no gene flow

Question 8

what does it mean if 1 condition is not met?

Answer 8

population is evolving

Question 9

what does no random mating affect

Answer 9

genotypes not alleles

Question 10

genetic drift

Answer 10

random fluctuations of allelic frequencies per generation that reduces genetic variation

Question 11

gene flow

Answer 11

movement of a individual or population that transfers alleles from one place to another. reduces genetic cariation

Question 12

founder effect

Answer 12

individuals isolate from population- causes alleles to be under/over represented

Question 13

bottleneck effect

Answer 13

change in environment reduces population size drastically

Question 14

directional selection

Answer 14

favored one way or another

Question 15

disruptive selection

Answer 15

favors extremes

Question 16

stabilizing selection

Answer 16

favors the median

Question 17

sexual dimporphism

Answer 17

males and females looks different

Question 18

intersexual

Answer 18

mate choice

Question 19

intrasexual

Answer 19

competition between same sex
