Question

A human ova that contains 23 chromosomes joins a human sperm that contains 23 chromosomes, resulting in a zygote that has 47 chromosomes. The process that creates this is called______________

Answer 1

Answer:

fertilization.

Explanation:

During fertilization, male and female gametes are fused to form a zygote. The male gametes in humans are called sperms. Sperms are formed by meiosis in sperm mother cells and have a haploid number of chromosomes (n=23). Similarly, the female gamete in humans is an egg which is a product of meiosis and is haploid (n=23). The fusion of these two haploid cells occurs in the oviduct of females in humans and form the diploid zygote with 2n=46. This process is called fertilization.
