Solution

The correct option is C $4 : 1$
The gametes are produced by the meiotic division. From a diploid, primary spermatocyte, four haploid spermatozoa are produced through meiosis. From a diploid primary oocyte, only one haploid ovum is formed. The remaining are polar bodies. These polar bodies do not develop as egg cell or ovum. Hence, the ratio between male gametes and female gametes produced from respective primary sex cells is 4 : 1.
Thus, the correct answer is option D.

I know this is a weird question but when I learn a a concept for the first time I always have weird questions.

Q- As this is true= Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.So only the haploid cells resulting from meiosis can be called sex cells in this case.

Then what is the name of the cell which is known to be diploid and divides into 4 daughter cells in meiosis? If it is a sex cell itself, then how can it be diploid if all sex cells are haploid.
