FAQs on Hardy Weinberg Equation Video Lecture - Biology Class 12 - NEET

1. What is the Hardy Weinberg equation?
Ans. The Hardy Weinberg equation is a mathematical equation that allows us to predict the frequencies of different genotypes in a population based on the frequencies of alleles. It is used to determine whether a population is evolving or in genetic equilibrium.
2. How is the Hardy Weinberg equation calculated?
Ans. The Hardy Weinberg equation is calculated using the formula: p^2 + 2pq + q^2 = 1, where p represents the frequency of one allele (dominant) and q represents the frequency of the other allele (recessive). The equation can be used to calculate the frequencies of the three possible genotypes: homozygous dominant (p^2), heterozygous (2pq), and homozygous recessive (q^2).
3. What does the Hardy Weinberg equation tell us about a population?
Ans. The Hardy Weinberg equation provides information about the genetic makeup of a population. If the observed frequencies of genotypes in a population match the frequencies predicted by the equation, then the population is said to be in genetic equilibrium, meaning that there is no evolution occurring. If the observed frequencies do not match the predicted frequencies, it suggests that the population is evolving.
4. How can the Hardy Weinberg equation be used to study evolution?
Ans. The Hardy Weinberg equation can be used to study evolution by comparing the observed frequencies of genotypes in a population to the frequencies predicted by the equation. If the observed frequencies differ from the predicted frequencies, it suggests that factors such as mutation, selection, migration, or genetic drift are causing the population to evolve. By analyzing these deviations, researchers can gain insights into the processes driving evolution.
5. What are the assumptions of the Hardy Weinberg equation?
Ans. The Hardy Weinberg equation makes several assumptions: 1) the population is large, 2) there is no migration, 3) there is no mutation, 4) there is no natural selection, and 5) mating is random. These assumptions are rarely met in natural populations, but the equation still provides a useful baseline for studying genetic equilibrium and evolutionary processes.
