In peas, Tall (T) is dominant to short (t), Round (R) is dominant to wrinkled (r) and Yellow pea color (Y) is dominant to green (y). A tall plant with round, yellow peas (Plant 1) was crossed to a short plant with round green peas (Plant 2) and the resulting progeny exhibited the following phenotypes: 310 Tall Round Yellow
105 Tall Wrinkled Yellow
290 Short Round Yellow
100 Short Wrinkled Yellow

e. The genotype of Plant 2 is tt Rr YY.

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
