Question

Explain why people who inherit one mutated allele of the brca1 gene have a higher likelihood of developing cancer

Answer 1

The genes BRCA1 and BRCA2 are the genes that suppress the growth of tumors in the body. If there is a mutation in any of these two genes, there will be a lower chance of inhibiting tumor growth. This will lead to a higher chance of cancer and tumor development in the body.
