White fruit color in summer squash is influenced by a dominant allele W, whereas colored fruit must be ww. In the
presence of ww, a dominant gene G results in yellow fruit, and homozygous gg results in green fruit. Give the F2
phenotypic ratios resulting from a cross of a true-breeding plant with white fruit (genotype WW GG) with a plant with
green fruit. What will be an ideal response?
ANSWER: 12/16 W__ __ __ white, 3/16 ww G __ yellow, 1/16 ww gg green

In your microbiology lab, your class is identifying bacteria. You are using dichotomous keys to aid in the identification process using the data from a variety of biochemical tests. What problems do you foresee in this procedure?
A. If you misread a biochemical test or write down the wrong result, the key will likely take you to an alternative organism that is not your unknown bacterium. B. Dichotomous keys are too sophisticated to read properly, so you are worried that there will be a large degree of error in your identification. C. The dichotomous key does not contain information on your bacterium. D. Dichotomous keys are not valid for identification.
