What are the steps to calculate allele and genotype frequencies using Hardy-Weinberg if given the number of individuals with the recessive phenotype?

Find $q^2$ (frequency of homozygous recessive). 2. Calculate $q$ (take the square root of $q^2$ ). 3. Calculate $p$ ( $p = 1 - q$ ). 4. Calculate $p^2$ , $2pq$ using the values of p and q.

What are the five conditions for Hardy-Weinberg equilibrium?

No mutation. 2. No selection. 3. No gene flow. 4. Infinite population size. 5. Random mating.

What is Hardy-Weinberg equilibrium?

A model describing a theoretical state where allele frequencies in a population remain constant from generation to generation.

Define allele frequency.

The relative proportion of an allele within a population.

Define genotype frequency.

The relative proportion of a genotype within a population.

What is the meaning of 'p' in Hardy-Weinberg equations?

Frequency of the dominant allele.

What is the meaning of 'q' in Hardy-Weinberg equations?

Frequency of the recessive allele.

What does $p^2$ represent in the Hardy-Weinberg equation?

Frequency of homozygous dominant genotype.

What is the difference between allele and genotype frequencies?

Allele frequencies (p, q) represent the proportion of each allele. Genotype frequencies ( $p^2$ , $2pq$ , $q^2$ ) represent the proportion of each genotype.
