Question

Question: Identify the mutation below that would be passed on to living offspring if it happened in a parent. (1 point)

Answer Choices:

( ) a substitution error that takes place in a somatic cells that causes skin cancer

( ) a chromosomal deletion that affects the ability of blood to carry oxygen

( ) an insertion mutation in a gamete that deactivates a gene for hair color

( ) a silent mutation in the genes of the pancreas cells that code for insulin

Answer 1

( ) an insertion mutation in a gamete that deactivates a gene for hair color

Reason: Only mutations in gametes (germline) can be inherited. Somatic mutations (skin cancer or pancreas cells) aren't passed on, and a large deletion affecting oxygen transport would likely be lethal and not produce living offspring.
