MUTATIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Mutations that do not affect the individual organism but can be passed on to the organism’s offspring are called:
A
somatic cell mutations
B
cancer
C
germ cell mutations
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: -Somatic mutations occur in non-reproductive cells and so won’t be passed on to offspring.

Detailed explanation-3: -Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene’s protein.

Detailed explanation-4: -A gene change in a body’s reproductive cell (egg or sperm) that becomes incorporated into the DNA of every cell in the body of the offspring. Germline mutations are passed on from parents to offspring.

Detailed explanation-5: -Human mutations arise in two major settings: the germline and soma. Germline mutations occur in sperm, eggs, and their progenitor cells and are therefore heritable. Somatic mutations occur in other cell types and cannot be inherited by offspring.
