Previous Page Next Page Page Question 9 (1 point) Question 1: A population has the following data: Genotype Number AA o aa Do a Chi-square test to determine if the population is at Hardy-Weinberg equilibrium. What is your hypothesis? The population is at HW equilibrium and have the expected HW genotype frequencies. The population is not at HW equilibrium and not have the expected HW genotype frequencies. The population can never reach HW equilibrium. The population is not at HW equilibrium and have the expected HW genotype frequencies.

Answer 1

The answer will be the population is at HW equilibrium & have the expected HW genotype frequencies (First option).

Explanation: If a population is not at HW equilibrium, then we can't expect it to have HW genotype frequencies. So, we can ignore last option. Third option is not appropriate if our target is to determine if the population is at HW equilibrium. So, we can ignore third option. As our target is to determine if the population is at HW equilibrium, we would consider that the population is at HW equilibrium & have required genotype frequencies. If after conducting a chi-square test, we found that there is significant difference exist between observed & expected values, then we will tell that the population are not in HW equilibrium. Thus, first option will be correct answer.
