Answer 2

The number of nuclei present in a zygote is B. one

Explanation:

• The nucleus of male gamete fuses with nucleus of female gamete in fertilisation process. So, there is only one fused nucleus in offspring.
• The gametes are haploid in nature and they carry half of genetic information from parents.
• As result of this process, zygote is formed which is diploid in nature.
• Zygote has all the necessary genetic information required for the offspring.
• It develops into embryo which is developed into offspring.
