Question

Please read the following table and select the correct option.
$\begin{array}{ccc}\text{I}& \text{Zygote}& \text{Haploid}\\ \text{II}& \text{Spermatogonia}& \text{Diploid}\\ \text{III}& \text{Primary spermatocyte}& \text{Haploid}\\ \text{IV}& \text{Spermatozoa}& \text{Haploid}\end{array}$

• A. Only I
• B. I, III and IV only
• C. Both II and IV
• D. Both II and III

Answer 1

The correct option is C Both II and IV

Diploid cells have two sets of chromosomes.

Zygote is a diploid cell formed by the fusion of two haploid cells, sperm and ovum.

Spermatogonia are diploid germ cells that produce the gametes.

Primary spermatocyte is formed due to differentiation of spermatogonium and hence is diploid.

Haploid cells have a single set of chromosomes.

Spermatozoa (sperms) are haploid cells, male gametes.
