Question
The number of nuclei present in a zygote is ______.
Options
none
one
two
four
Solution
The number of nuclei present in a zygote is one.
Explanation:
Sperm and ovum fuse to form the fertilised egg called zygote. During fertilisation, the nuclei of the sperm and the egg fuse to form a single nucleus. This results in the formation of a fertilised egg or zygote. Thus, a zygote is formed with a single nucleus, and this completes the process of fertilisation.
