populations

Question 1

how do species exist

Answer 1

as one or more populations

Question 2

what is a population

Answer 2

group of organisms of the same species occupying a particular space at a particular time that can potentially interbreed

Question 3

what is a gene pool

Answer 3

range of alleles in a population

Question 4

was is allele frequency

Answer 4

how often an allele occurs in a population

Question 5

what is hardy-weinbergs principle

Answer 5

mathmatical model that predicts the allele frequencies from generation to generation

Question 6

what are the conditions in which the hardy-weinbergy principle applies

Answer 6

-large population
- no immigration/emigration
- no mutations arising
- no natural selection

Question 7

what is the hardy-weinberg equation

Answer 7

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

frequency of dominant allele = p
frequency of recessive allele = q

p + q = 1

p^2 = freq of homozygous dominant genotype
2pq = freq of heterozygous genotype
q^2 = freq of homozygous recessive genotype
