पर्याय
True
False
उत्तर
This statement is True.
Explanation:
The first step in reproduction is the fusion of a sperm and an ovum. When sperm comes in contact with an egg, one sperm may fuse with the egg. Such fusion of the egg and the sperm is called fertilisation. During fertilisation, the nuclei of the sperm and the egg fuse to form a single nucleus, forming a fertilised egg or zygote.
