Individuals can evolve during their lifetime.

Based on the previous question, what would be the frequency of a in the next generation, taking into account the mutation rate?

There is a mathematical way to demonstrate whether evolution has occurred. 

Tay–Sachs disease is an autosomal recessive disorder. Homozygous recessive individuals lack a key enzyme called hexosaminidase A, which presents as progressive mental and motor deterioration until death occurs around age 5. Heterozygous individuals, known as Tay–Sachs carriers, typically do not develop symptoms of the disease. Tay–Sachs disease was historically more prevalent within populations of Ashkenazi Jews, Pennsylvania Dutch, southern Louisiana Cajuns, and eastern Quebec French Canadians. Today, individuals descended from these populations are more likely to be carriers of the Tay–Sachs allele; however, genetic testing within these populations has largely eliminated the occurrence of Tay–Sachs disease. For a randomly mating population, calculate the Tay–Sachs frequency, which is the frequency of the recessive allele, if 1 in 3,600 individuals develops Tay–Sachs disease. (Use four decimals in your calculations.)
