What parts of the Hardy Weinberg equation represent gene frequency?
The p and q variables in the Hardy-Weinberg equation represent the frequencies of the two alleles in a population. The equation is often written as p^2 + 2pq + q^2 = 1, where p and q represent the frequencies of the dominant and recessive alleles, respectively.
What does p2 represent in the Hardy-Weinberg equation?
In the Hardy-Weinberg equation, p2 represents the frequency of the homozygous dominant genotype in a population for a specific gene. It represents the proportion of individuals in the population that have two copies of the dominant allele.
The Hardy-Weinberg formula and what each of the terms mean?
formula: p2 + 2pq + q2 = 1 p+q=1 p = dominant (A) allele frequency q = recessive (a) allele frequency q2 = homozygous recessive frequency p2 = homozygous dominant frequency 2pq = heterozygous frequency
What are some examples of Hardy-Weinberg problems and how can they be solved?
Hardy-Weinberg problems involve calculating allele frequencies in a population to determine if it is in genetic equilibrium. Examples include calculating the frequency of homozygous dominant, heterozygous, and homozygous recessive individuals. These problems can be solved using the Hardy-Weinberg equation: p2 2pq q2 1, where p and q represent the frequencies of the two alleles in the population.
How would selection against heterozygous individuals over many generations affect the frequencies of homozygous individuals?
Selection against heterozygous individuals would cause the frequencies of homozygous individuals to increase over generations as alleles that result in heterozygote disadvantage are progressively removed from the population. This process can lead to more pronounced differences between the two homozygous genotypes.
