MUTATIONS

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: -The sperm and egg pass from parents to their children, so the mutation is inherited. You can’t inherit somatic mutations because they occur randomly in cells that aren’t the sperm or egg.

Detailed explanation-3: -If a mutation occurs in a germ-line cell (one that will give rise to gametes, i.e., egg or sperm cells), then this mutation can be passed to an organism’s offspring. This means that every cell in the developing embryo will carry the mutation.

Detailed explanation-4: -If a parent carries a gene mutation in their egg or sperm, it can pass to their child. These hereditary (or inherited) mutations are in almost every cell of the person’s body throughout their life. Hereditary mutations include cystic fibrosis, hemophilia, and sickle cell disease.

Detailed explanation-5: -These occur in all cells in the developing body-except the sperm and egg. Somatic mutations can’t pass from parents to their children (hereditary) because traits are passed only from the sperm and egg.
