How many meiotic divisions are required for the formation of 50 zygotes?

The correct option is B 63

In spermatogenesis, 52 sperm can be produced in 13 meiotic divisions.

However, 50 eggs will require 50 meiotic divisions, because one meiotic division in oogenesis produces a single egg. Use the formula x + x/4, where x is the number of seeds.

Therefore 50 + 50/4 = 50+ 12.5 = 62.5 = approx 63 divisions.

So, the correct answer is '63'.
