Which of the following is not a factor that affects Hardy-Weinberg equilibrium?a)Vegetative propagationb)Migrationc)Mutationd)Genetic driftCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Answer

Vegetative propagation is a kind of asexual reproduction that occurs in plants, on the other hand migration, mutations and genetic drift are the factors that affects Hardy-Weinberg Equilibrium which states that_ the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors above.

Answer

Hardy-Weinberg Equilibrium

The Hardy-Weinberg equilibrium is a principle in population genetics that describes the behavior of genetic traits in a population over time. It provides a mathematical model that predicts the frequencies of genotypes and alleles in a population that is not evolving.

Factors Affecting Hardy-Weinberg Equilibrium

The Hardy-Weinberg equilibrium assumes certain conditions in a population that must be met in order for the model to apply accurately. Deviations from these conditions can disrupt the equilibrium and lead to changes in allele frequencies. The factors that can affect the Hardy-Weinberg equilibrium include:

1. Migration (Gene Flow): Migration refers to the movement of individuals and their genes between different populations. When individuals migrate from one population to another, they bring new alleles with them, which can alter the allele frequencies in both populations. This disrupts the equilibrium and introduces new genetic variation.

2. Mutation: Mutation is the process by which genetic material is altered or changed. It introduces new alleles into a population, which can lead to changes in allele frequencies. Mutations can occur spontaneously or as a result of environmental factors, and they can introduce new genetic variation into a population, disrupting the Hardy-Weinberg equilibrium.

3. Genetic Drift: Genetic drift refers to the random fluctuations in allele frequencies that occur in small populations. It is a result of chance events rather than natural selection. Genetic drift can lead to the loss of certain alleles or fixation of others, causing changes in allele frequencies and disrupting the Hardy-Weinberg equilibrium.

4. Vegetative Propagation: Vegetative propagation is a method of asexual reproduction in plants where new individuals are produced from the vegetative parts of the parent plant, such as stems, roots, or leaves. This process does not involve the exchange of genetic material or the introduction of new alleles. As a result, it does not affect the allele frequencies in a population and therefore does not disrupt the Hardy-Weinberg equilibrium.

Conclusion

In summary, the factors that affect the Hardy-Weinberg equilibrium include migration, mutation, and genetic drift. These factors can introduce new alleles, alter allele frequencies, and disrupt the equilibrium. On the other hand, vegetative propagation does not involve the exchange of genetic material and therefore does not affect allele frequencies or disrupt the equilibrium.
