Answer:

a. Each cell has half the normal number of chromosomes and the cells are usually genetically different

Explanation:

Sperm cells, also known as spermatozoa or male gametes, are cells that contain a single set of chromosomes, i.e., they are haploid (n) cells. In fertilization, an egg cell (female gamete) and a sperm cell fuse to form a diploid (2n) zygote cell. Moreover, crossing over or recombination is the interchange of genetic material that occurs in the germline (i.e., both female gametes and male gametes). Crossing over occurs between non-sister chromatids during meiosis (prophase I). As a consequence of this process, gametes are not genetically aren't identical to one another.

Sperm cells are gametes produced in the testicular organs of a male human or animal.

The correct option is :

(a)  Each cell has half the normal number of chromosomes, and the cells are usually genetically different.

Sperm cells

  • Sperm cells are gametes or germ cell produced in testicles of a male.

  • Sperm cells carry 23 that is half of the total number of chromosome.

  • They are produced through the process of meiosis.

  • In each and every organism, the sperm cells are genetically different.

Hence, the only correct option is (a) Each cell has half the normal number of chromosomes and the cells are typically genetically different.
