Hardy-Weinberg Practice 4 (1/27) The ability to taste PTC is due to a single dominant allele "T". You sampled 215 individuals, and determined that 150 could detect the bitter taste of PTC and 65 could not. Calculate one set of potential frequencies.

Is it in equilibrium? AKA: Do the frequencies change (or not) over generations? AKA: Is this population evolving?

Is it in equilibrium? AKA: Do the frequencies change (or not) over generations? AKA: Is this population evolving? How can you tell? What is our textbook definition of evolution? So, what do you need to know?

Next generation You sampled 450 individuals, and determined that 400 could detect the bitter taste of PTC and 50 could not. Is it in equilibrium?

How else can we tell? If the frequencies are p2, 2pq, and q2

A locus that affects susceptibility to a degenerative brain disease has two alleles, A and a. In a population, 16 people have AA, 92 have Aa, and 12 have aa. Is this population evolving?
