How are genetic mutations passed from parent to offspring? a. sex cells divide to create new cells. b. mutated gametes (sex cells) fuse to create offspring. c. genetic mutations occur during dna replication. d. genetic mutations only occur during meiosis, never mitosis.

Ans. (B). Mutated gametes (sex cells) fuse to create offspring.

Genetic mutations or germline mutations can be defined as permanent change in the DNA sequence of germ cells (cells, which form ovum and sperm). These mutations can pass from one generation to other, when a mutated sperm or mutated oocyte (gametes) get fertilized with other oocyte or sperm.

A germline mutation, present in a single-celled zygote will present in all cells of a muticellular organism, as single-celled zygote divides and produce all of the cells in that organism.  

Thus, the correct answer is option (B).

the answer would be 3

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
