Prompt

Sometimes, changes or “mutations” occur that prevent genes from doing their job properly. Certain mutations in the BRCA genes make cells more likely to divide and change rapidly, which can lead to cancer.

Given your understanding of meiosis and inheritance explain the following statement: “If either your mother or your father has a BRCA1 or BRCA2 gene mutation, you have a 50% chance of having the same gene mutation.”

Expert Solution

Introduction:

BRCA 1 and BRCA 2 are two tumor suppressor genes that express proteins that help in DNA repair. The normal function of BRCA genes is to prevent cancer but due to mutations they become altered and cannot suppress the cancerous cells anymore. BRCA stands for BReast CAncer.
