Topic 7 - Populations and Evolution Flashcards
1
Q
what is a population
A
a group of organisms of the same species living in a particular area at a particular time.
2
Q
what is a gene pool
A
the complete range of alleles in a population
3
Q
what is allele frequency
A
how often an allele occurs in a population
4
Q
what does the Hardy-Weinberg principle predict
A
- allele frequencies wont change from one generation to the next
- if it is a large population..
- no immigration
- no emigration
- no mutations
- no natural selection
- random mating
5
Q
in the Hardy Weinberg principle, what does p^2 stand for
A
frequency of homozygous dominant genotype
6
Q
in the Hardy Weinberg principle, what does 2pq stand for
A
frequency of heterozygous genotype
7
Q
in the Hardy Weinberg principle, what does q^2 stand for
A
frequency of homozygous recessive genotype
8
Q
what is the hardy weinberg equation
A
p^2 + 2pq + q^2 = 1
9
Q
what is the hardy weinberg equation
A
p^2 + 2pq + q^2 = 1
