Dr. Pratt is interested in identifying genes related to reduced eye contact in individuals with autism spectrum disorder. To identify the genes associated with this trait, Dr. Pratt will probably conduct a
Select one:
a. reverse genetic screen.
b. twin study.
c. forward genetic screen.
d. knockout gene experiment.
To identify the genes associated with this trait, Dr. Pratt will probably be conducting;
d. knockout gene experiment (By knocking out the gene if the expression of the trait is lost it will be confirmed that the gene knocked out is responsible for the trait)

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
