Answer:

Explanation:The process of fusion of sperm with egg (ovum) to produce zygote is called fertilization. It is the crucial and primary stage of sexual reproduction. During sexual intercourse, the penis ejaculates millions of sperms into the vagina of the woman. Sperms will travel through the uterus to oviducts. At oviduct, one out of million sperms fertilizes the released ovum. The fertilized egg develops into a zygote. Without the fusion of gametes, sexual reproduction is futile. It doesn’t occur in asexual reproduction.

Human fertilization and development

Fertilization is the process in which haploid gametes fuse to form a diploid cell called a zygote. To ensure that each zygote has the correct number of chromosomes, only one sperm can fuse with one egg.

In animals, there are two types of fertilization, internal and external. Internal fertilization happens in the female body. External fertilization happens outside of the body. Mammals, birds, and reptiles use internal fertilization.

The process of fertilisation helps to restore the total number of chromosomes in the organism. The zygote develops to form a new individual which is necessary for the continuation of the species. It creates genetic variation and helps to maintain biodiversity.
