Question

what does the hardy-weinberg equilibrium measure? goodness of fit population size genetic diversity changes in allele frequencies

Explanation:

Hardy-Weinberg equilibrium provides a baseline model of a non-evolving population. By comparing observed allele/genotype frequencies to those predicted by the equilibrium, it detects if allele frequencies are changing (a sign of evolution). The other options are incorrect: it does not measure population size directly, genetic diversity, or goodness of fit as its primary purpose.

Answer:

D. changes in allele frequencies
