Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Sperm and eggs are known as
A
sex cells
B
sex chromosomes
C
sex genes
D
true-breeding factors
Explanation: 

Detailed explanation-1: -These sex cells are also called reproductive cells or gametes. Sperm cells are produced in men’s testicles and egg cells are produced in women’s ovaries. Sex cells are different from other cells in one special way: Put simply, they only have one half of the total amount of human genetic information.

Detailed explanation-2: -Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.

Detailed explanation-3: -An egg will always have an X chromosome, since the woman’s sex chromosome pair only has Xs. Sperm can have either an X chromosome or a Y chromosome. If a sperm with an X chromosome fertilizes the egg, the new cell will have two X chromosomes. One came from the father’s sperm and one came from the mother’s egg.

Detailed explanation-4: -A simple definition of a somatic cell is that it is a non-sex cell (a very broad and not always accurate description). In humans, somatic cells contain 46 individual chromosomes, organised into 23 pairs of chromosomes.
