One of the deadliest animals on earth is the rough skinned newt. It produces highly toxic skin toxins. In the 1970s, three hunters were found dead while camping in Western Oregon when they accidentally boiled a rough skinned newt in their coffee pot. Scientists discovered that they were becoming more toxic due to a common predator: the garter snake. As garter snakes were growing more immune to their toxins, rough skinned newts were growing more toxic in what is known as an “evolutionary arms race”. Though the genes for the garter snake immunity are most likely polygenic, however, let us assume that the immunity is caused by a single dominant allele for this exercise. Those without the dominant gene (the recessive genotype), are NOT immune to the toxins of the rough skinned newt.

In 1975, in a population of 88 garter snakes on the coast of Oregon, 54 of them exhibit the recessive genotype are therefore not immune to the rough skinned newt’s toxin.

What is the frequency for the recessive genotype (q^2)?

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
