18.1 population genetics Flashcards
1
Q
gene pool definition
A
all the alleles of all the genes of all the individuals in a population at a given time
2
Q
allelic frequency definition
A
number of times an allele occurs within the gene pool
3
Q
Hardy- Weinberg principle equation
A
p^2 + 2pq + q^2= 1
p + q=1
4
Q
what is q?
A
allelic frequency of recessive allele
5
Q
what is p?
A
allelic frequency of dominant allele
6
Q
what is q^2?
A
homozygous dominant individual
7
Q
what is p^2?
A
homozygous recessive individual
8
Q
what is 2pq?
A
heterozygous individual
9
Q
what are the 5 conditions for Hardy- Weinberg equation?
A
- no mutations arise
- no gene flow
- no selection of alleles
- large population
- mating within the population is random
