MUTATIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
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: 

Detailed explanation-1: -The answer is gametes. Mutations that occur in sex cells can be passed to new generations of the species.

Detailed explanation-2: -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-3: -Mutations can occur in either cell type. If a gene is altered in a germ cell, the mutation is termed a germinal mutation. Because germ cells give rise to gametes, some gamete s will carry the mutation and it will be passed on to the next generation when the individual successfully mates.

Detailed explanation-4: -Germline mutations occur in gametes. These mutations are especially significant because they can be transmitted to offspring and every cell in the offspring will have the mutation. Somatic mutations occur in other cells of the body.

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.
