Describe the process of fertilization

Explanation:

Fertilization is the process by which haploid gametes (n- sperm and egg) fuse together to form a diploid cell called ZYGOTE. A gamete is a reproductive or sex cell produced by a sexually-reproducing organism during meiosis. Diploid organisms produce gametes that contains one set of chromosomes i.e haploid. Male organisms produce sperm while female organisms produce egg/ovum.

To ensure that the zygote, which grows into the full organism, has the correct number of chromosomes, only one sperm can fuse with one egg. It is worthy to note that, fertilization can either occur internally (union of sperm and egg within the body of the female parent) or externally (joining of gametes outside the body).
