Which one of the following statements best describes the major difference between sex determination in Drosophila and in humans?

You should place any soiled clothing from a sexual assault victim into a red plastic bag.

A heterozygous parent self fertilizes and the progeny are collected. Ten of these offspring form wild-type plants and nine are homozygous recessive mutants? Calculate the probabilities of this distribution by chi-square analysis (report the P value in the chart closest to your chi-square value).

Common names for activated charcoal include all of the following, EXCEPT:

Assume that the genes for tan body and bare wings are 8 map units apart on chromosome II in Drosophila. Assume also that a tan-bodied, bare-winged female was mated to a wild-type male and that the resulting F1 phenotypically wild-type females were mated to tan-bodied, bare-winged males. Of 1000 offspring, what would be the expected of wild-type offspring, and in what numbers would they be expected?

The gastrointestinal digestion of nutrients can be regulated by neuro-humoral stimuli. Please list the 4 classic hormones that were covered in the class: 1. _______________________________________, 2. ________________________________________, 3.  ___________________________________, and 4. ________________________________________.

The EMT’s primary responsibility to the patient who has been poisoned is to:

The phenomenon in which many genes influence the development of a single phenotypes is called _____.

Law enforcement personnel request your assistance for a 30-year-old man who they pulled over for erratic driving. The patient became acutely violent while he was being questioned, which required one of the officers to subdue him with a Taser. When you arrive and assess the patient, you find that he is very agitated and is experiencing apparent hallucinations. His skin is flushed and diaphoretic. You should:

The genes for miniature wings (m) and garnet eyes (g) are linked on chromosome 1 in Drosophila. Phenotypically wild-type females that were heterozygous for both loci were mated to miniature-winged males with garnet eyes.  The resulting progeny were: 38 miniature wings, red eyes 42 wild-type wings, garnet eyes 5 miniature wings, garnet eyes 5 wild-type wings and eyes The best explanation for this is:
