Question: Compare the actual frequencies abovewith the expected frequencies of alleles and genotypes. Is thispopulation in Hardy-Weinberg equilibrium?

What process could account for the discrepancies between theactual and expected frequencies of DDand dd?

Explanation / Answer

As we see there is a difference between the actual frequencyand expected frequency. The expected frequency is according to Hardy-weinbergequilibrium while the actual frequency is not matching. This shows that the population taken under consideration isevolving. No population stays constant,it keeps evolving. This evolution accounts for the discrepancies in DD anddd.
