Question

Fertilization is fusion of

• A. Diploid spermatozoan with diploid ovum to form diploid zygote
• B. Haploid spermatozoan with diploid ovum to form diploid zygote
• C. Diploid spermatozoan with haploid ovum to form diploid zygote
• D. Haploid spermatozoan with haploid ovum to form diploid zygote

Answer 1

The correct option is D Haploid spermatozoan with haploid ovum to form diploid zygote

Fertilization is the process of fusion of a haploid sperm (spermatozoan) with a haploid ovum. During this process, the diploid cell is formed called as a zygote. A zygote is the initial stage of formation of multicellular organisms. Thus, the correct answer is option D.
