Document Summary
Biological science, 3rd canadian edition (freeman et al. ) Chapter 23 evolutionary processes: cystic fibrosis is a genetic disorder in homozygous recessives that causes death during the teenage years. Explanation: ideally, students can answer this question without a calculator. This example uses different frequencies from those in the chapter essay. Hardy-weinberg expectations for this gene, what percentage of the population must be heterozygous for this trait: 16, 32, 40, 48, 60% Explanation: this question is somewhat challenging because students must figure out the frequency of homozygous recessives (0. 36) and use this to calculate q (0. 6) and p (0. 4) and then. Copyright 2019 pearson canada, inc: for biologists studying a large flatworm population in the lab, which hardy-weinberg condition is most difficult to meet, no selection, no genetic drift, no gene flow, no mutation, random mating. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production.
