Hardy-Weinberg principle

A fundamental concept in population genetics that describes conditions under which allele and genotype frequencies remain constant across generations.

2
New cards

No mutation

A condition stating that the rate of mutation must be negligible for Hardy-Weinberg equilibrium.

3
New cards

Random mating

A condition that requires individuals to mate randomly, without preference for certain genotypes.

4
New cards

No gene flow

The condition requiring no migration of individuals into or out of the population for Hardy-Weinberg equilibrium.

5
New cards

No genetic drift

A condition that states the population must be large enough to avoid random changes in allele frequencies.

6
New cards

No selection

A condition where all genotypes must have equal survival and reproductive rates.

Hardy-Weinberg equations

Equations used to calculate expected allele and genotype frequencies in a population under equilibrium.

8
New cards

Allele frequency equation

p+q=1p + q = 1 where pp is the frequency of the dominant allele and qq is the frequency of the recessive allele.

9
New cards

Genotype frequency equation

p2+2pq+q2=1p^2 + 2pq + q^2 = 1 which describes the frequencies of homozygous dominant, heterozygous, and homozygous recessive genotypes.

10
New cards

Frequency of homozygous recessive genotype (q^2)

The value used to calculate q and subsequently p in Hardy-Weinberg problems.

11
New cards

Solving for q

To calculate q, take the square root of the frequency of the homozygous recessive genotype (q^2).

12
New cards

Finding frequency of dominant allele (p)

Calculated by subtracting q from 1 in Hardy-Weinberg calculations.

Deviations from Hardy-Weinberg Equilibrium

Changes in allele frequencies due to factors such as mutation, natural selection, genetic drift, or gene flow.
