A dominant mutation in Drosophila called Delta causes changes in wing morphology in Delta / + heterozygots. Homozygosity for this mutation (Delta / Delta) is lethal. In a population of 150 flies, it was determined that 60 bad normal wings and 90 had abnormal wings. a. What are the allele frequencies in this population? b. Using the allele frequencies calculated in part (a), how many total zygotes must be produced by this population in order for you to count 160 viable adults in the next generation? c. Given that there is random mating, no migration, and no mutation, and ignoring the effects of genetic drift, what are the expected numbers of the different genotypes in the next generation if 160 viable offspring of the population in part (a) are counted? d. Is this next generation at Hardy-Weinberg equilibrium? Why or why not?
