Study Notes
Hardy-Weinberg Equilibrium
- Describes the genetic makeup of a population that is not evolving at a specific locus.
- The population is in Hardy-Weinberg equilibrium if the observed data matches the expected values.
- The condition for a population to be in Hardy-Weinberg equilibrium is:
- the population is very large
- there is no mutation
- there is no genetic drift
- there is no gene flow
- mating is random
- there is no natural selection
- In a population in Hardy-Weinberg equilibrium, the frequency of alleles and genotypes remains constant from generation to generation.
- Mendelian inheritance preserves the genetic variation in a population.
- The Hardy-Weinberg equation describes the frequency of alleles in a population.
- If the frequency of one allele is 0.2, the frequency of the other allele is 0.8.
- The sum of the frequencies of the two alleles is 1.
- The Hardy-Weinberg equation is: p^2 + 2pq + q^2 = 1.
- The probability of a zygote having a particular allele or genotype is calculated using the Hardy-Weinberg equation.
- The probability of a zygote having the CR allele is p^2.
- The probability of a zygote having the Cw allele is q^2.
- The probability of a zygote having the CwCw genotype is q^2.
- The probability of a zygote having the CR allele in a population in Hardy-Weinberg equilibrium is p.
- The Hardy-Weinberg equation does not require a population to be in genetic drift or mutation.
Test your knowledge of the Hardy-Weinberg equation and its application in population genetics. This quiz will assess your understanding of how genetic makeup is expected to remain constant in a non-evolving population. Explore the implications of observed data that deviate from expected values and identify potential evolutionary changes.
