Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Mutations are only passed on to offspring when they happen in
A
somatic cells
B
gamete cells
C
prokaryotic cells
D
the mitochondria
Explanation: 

Detailed explanation-1: -Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.

Detailed explanation-2: -Germ-line mutations occur in reproductive cells (sperm or eggs) and are passed to an organism’s offspring during sexual reproduction. Somatic mutations occur in non-reproductive cells; they are passed to daughter cells during mitosis but not to offspring during sexual reproduction.

Detailed explanation-3: -You can inherit germline genetic mutations. In this type of mutation, the DNA change happens in reproductive cells (egg or sperm). The sperm and egg pass from parents to their children, so the mutation is inherited.

Detailed explanation-4: -Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations.

Detailed explanation-5: -A mutation that occurs in body cells that are not passed along to subsequent generations is a somatic mutation. A mutation that occurs in a gamete or in a cell that gives rise to gametes are special because they impact the next generation and may not affect the adult at all.
