Question

HELP!!!! WILL GIVE BRAINLIEST!!

Answer 1

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.
