2.2 - Evolution

Question 1

evolution definition

Answer 1

the gradual change in the characteristics of a species over generations caused by natural selection, sexual selection and genetic drift

Question 2

genetic drift definition

Answer 2

the random change in the frequency of alleles in a population

Question 3

where is genetic drift significant

Answer 3

in small populations where alleles can be lost easily

Question 4

natural selection

Answer 4

the non random increase in the frequency of advantageous alleles which will increase the chance of survival and the non random decrease of deleterious alleles which cause harm to an organism

Question 5

source of new alleles in a population

Answer 5

mutation

Question 6

hardy-weinberg formulae

Answer 6

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

Question 7

p value hardy-weinberg

Answer 7

frequency of dominant allele

Question 8

q value hardy-weinberg

Answer 8

frequency of recessive allele

Question 9

p^2 value hardy-weinberg

Answer 9

frequency of dominant homozygous genotype

Question 10

q^2 value hardy-weinberg

Answer 10

frequency of recessive homozygous genotype

Question 11

2pq value hardy-weinberg
