In which of the following ways have scientists been able to improve the classification system first devised by linnaeus in the early 1700s?

advances in gene and protein sequencing have led to a better understanding of the evolutionary relationships between species.
developing genetic engineering techniques has allowed us to add entire kingdoms to the original classification system.
improved tracking and mapping technology has provided better information on the geographical ranges of individual species.
knowing the complete sequence of an organism's dna allows us to name it more accurately.

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
