unit 3.1

Question 1

Theory of island biogeography helps do what

Answer 1

understand why some areas have more diversity than others

Question 2

was is the theory of island biogeography based on

Answer 2

the surface area/ size of region
degree of isolation

Question 3

diversity of an area is a function of 2 things

Answer 3

the rate of immigration
the rate of extinction

Question 4

rate of immigration vs rate of emigration

Answer 4

immigration the the colonizaiton of an area by new species
emigration is the loss of species from that area

Question 5

species equilibrium

Answer 5

when the rate of immigration = the rate of extinction

Question 6

low # of species is a high or low immigration curve rate

Answer 6

high rate

Question 7

high # of species is a high or low immigration curve rate

Answer 7

low rate

Question 8

low # of species is a high or low extinction curve rate

Answer 8

low rate

Question 9

high # of species is a high or low extinction curve rate

Answer 9

high rate

Question 10

know the immigration/extinction (near/far) (small/large) graph

Answer 10

draw it

Question 11

will an island small and near have more species than an island large and far

Answer 11

yes

Question 12

what can island biogeography be applied to

Answer 12

patches

Question 13

intermediate disturbance hypothesis curve

Answer 13

upside down U

Question 14

low disturbances lead to what diversity

Answer 14

low diversity

Question 15

high disturbances lead to what diversity

Answer 15

low diversity

Question 16

intermediate disturbances lead to what diversity

Answer 16

high diversity

Question 17

why is a medium amount of disturbances ideal

Answer 17

lack of disturbance lets competitors take over and too much disturbances limit the organisms

Question 18

geneticallly speaking . what is evolution

Answer 18

the frequencies of alleles or genotypes in the population must change over time

Question 19

genotype def

Answer 19

the genetic make up used to produce a trait

Question 20

alleles def

Answer 20

different forms of a particulr gene

Question 21

phenotype def

Answer 21

the actual expression of a particular trait based on the genotype

Question 22

homo dom of AA pheno is

Answer 22

A

Question 23

hetero Aa pheno is..

Answer 23

A

Question 24

homo rec of aa pheno is…

Answer 24

a

Question 25

gene pool def

Answer 25

total # of genes in a population

Question 26

allele frequency def

Answer 26

the fraction of the gene pool represented by a particular allele

Question 27

5 ways to get evolution

Answer 27

natural selection mutation gene flow non random mating genetic drift

Question 28

natural selection def

Answer 28

if you arent the best. ope. you die.

Question 29

mutation def

Answer 29

an important facotr. abrubt change

Question 30

gene flow def

Answer 30

migration , moving genetic material from 1 pop to another

Question 31

non random mating def

Answer 31

individuals tend to mate more frequently if they look alike

Question 32

genetic drift def

Answer 32

randomness in small populations founder effect or bottleneck effect

Question 33

sexual selection def

Answer 33

when reproductive traits are selected at the potential compromise of survival reproduction > survival

Question 34

when will evolution not occur

Answer 34

if all 5 of the options are not met so you need to have no mutations, no gene flow, have random mating, no genetic drift, and no natural selection

Question 35

genetic equilibrium

Answer 35

where there is no change in allele frequency (year after year)

Question 36

p is

Answer 36

freq of Dominant

Question 37

q is

Answer 37

freq of recessive

Question 38

p+q=1 and what else

Answer 38

1-p = q and 1-q = p

Question 39

hardy weinberg equation def

Answer 39

p^2 + 2pq + q^2 = 1

Question 40

p^2 is what

Answer 40

frequency of homo dom geno

Question 41

2pq is what

Answer 41

frequency of hetero geno

Question 42

q^2 is what

Answer 42

freq of homo rec geno

Question 43

what does the hardy weinberg equation do

Answer 43

links allele frequencies and genotype frequencies
