SBI3U 2011 Hardy- Weinberg Practice Problems 1. The ability to taste bitter substances is due to a single dominate allele "T". You sampled 215 individuals in Hill Park, and determined that 150 could detect the bitter taste of PTC and 65 could not. Calculate all of the allele and genotype frequencies. 2. After graduation, you and 19 friends build a raft, sail to a deserted island, and start a new population, totally isolated from the world. Two of your friends carry (that is, are heterozygous for) the recessive cf allele, which in homozygotes causes cystic fibrosis. Assuming that the frequency of this allele does not change as the population grows, what will be the instance of cystic fibrosis on your island?
