On fertilization of egg nucleus with sperm nucleus

• A. Second maturation is completed
• B. Zygote is formed
• C. First polar body is formed
• D. First maturation is completed

Answer 1

The correct option is B Zygote is formed

Fertilization occurs when the nucleus of both, a sperm and an egg fuse to form a diploid cell, known as a zygote. A zygote is a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum. An organism in the early stages of growth and differentiation, from fertilization to the beginning of the third month of pregnancy (in humans) is called as an embryo, after that, an embryo is called a fetus.
