Question

mutations can occur in the chromosomes of all types of cells. mutations that are passed on to offspring must occur in
a gametes
b body cells
c stem cells
d somatic cells

Explanation:

Mutations passed to offspring must be in cells that contribute genetic material to the next generation. Gametes (sperm/egg) are reproductive cells that fuse during fertilization, so their mutations are inherited. Body cells (somatic cells) and stem cells (unless they become gametes) do not pass mutations to offspring.

Answer:

A. gametes
