Female mosquitoes spread diseases when they bite humans to obtain blood. It is only the females that do the biting. Research is being done
to alter the DNA of the male mosquitoes. The altered males could
then mate with the normal female mosquitoes. All of the resulting
offspring would have wing defects that prevent them from flying.
The method used to alter the male mosquitoes is an example of an
application of

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
