Answer
4:01
Explanation
Solution
From a diploid, primary spermatocyte, four haploid spermatozoa are produced through meiosis. While, from a diploid primary oocyte, only one haploid ovum is formed, rest are polar bodies. Hence, the ratio between male gametes and female gametes produced from respective primary sex cells is 4 : 1.
