Suppose that a geneticist discovers & new mutation in Drosophila melanogaster that causes the flies to shake and quiver: She calls this mutation quiver; qu, and determines that it is due to an autosomal recessive gene. She wants tO determine whether the gene encoding quiver is linked to the recessive gene for vestigial wings, Vg: She crosses a fly homozygous for quiver and vestigial traits with a fly homozygous for the wild-type traits_ and then uses the resulting F1 females in a testcross. She obtains the flies from this testcross. Phenotype Number of flies vg qu 230 vg qu 224 Vg qu 97 vg qu 99 Test the hypothesis that the gencs quiver and vestigial assort independently by calculating the chi-squared, X?, for this hypothesis. Provide the X? to one decimal place. X2 Does the X2 value support the hypothesis that the quiver and vestigial genes assort independently Why or why not? Use the partial table of critical values for X2 calculations to test this hypothesis. No, the X? = value indicates that the observed progeny are significantly different from what would be expected with independent assortment of the two genes. No, the X2 = value indicates that there are tOO many phenotypes for independent assortment Yes, the X2 value indicates that the genes vestigial and quiver assort independently: Yes, the X? = value indicates that the observed and expected number of progeny are equal in number:
