HELP!!!! WILL GIVE BRAINLIEST!!
Medical research has uncovered a mutated gene, BRCA1 and BRCA2, that can be passed down in families and causes 10 percent of breast cancer cases. Those who have this gene have an 87 percent chance of getting breast cancer and a 50 percent chance of getting ovarian cancer. Some who have the gene have made the decision to go ahead and have a mastectomy before cancer gets a chance to present itself. One famous case is actress Angelina Jolie, who had a double mastectomy because she carried the BRCA1 gene. Do some research to see if this is the only option for those who carry the BRCA1 or BRCA2 gene. What would be the side effects of this treatment? Then discuss your opinion: Is opting for this treatment a wise course or not?

Answer: Everyone has two copies of the BRCA1 and BRCA2 genes, one copy inherited from their mother and one from their father. Even if a person inherits a BRCA1 or BRCA2 mutation from one parent, they still have the normal copy of the BRCA1 or BRCA2 gene from the other parent.

Explanation:

When a BRCA gene is mutated, it may no longer be effective at repairing broken DNA and helping to prevent breast cancer. Because of this, people with a BRCA gene mutation are more likely to develop breast cancer, and more likely to develop cancer at a younger age.Both women AND men with an abnormal breast cancer gene have a 50% risk of passing the abnormal gene on to their children. All women should tell their doctors about the health histories of their mother's AND their father's families, especially any history of breast and ovarian cancer.
