Why is the Hardy-Weinberg equation important when it comes to public health issues?
1) It can be used to predict the frequency of recessive genetic conditions in a human population.
2) It is not useful in studying genetic drift or natural selection.
3) It can predict exactly how many people will be born with sickle-cell anemia every year.
4) It will not help scientists to understand if a population of organisms is changing.
5) It is not used to study human populations.
