Good Evening Sir,
Q:- How many meiotic divisions are required to produce 40 zygotes of frog? Explain.
Asked by Sahil Kumar | 17th Mar, 2017, 06:30: PM
Zygotes are formed by the union of male gametes (sperms) and female gametes (egg).
To produce 40 zygotes,
- 40 meiotic divisions are necessary to produce 40 haploid egg cells because generally 1 egg is produced by the meiosis of 1 oogonium.
- 10 meiotic divisions are necessary to produce 40 haploid sperms because 4 spermatids are produced by the meiosis of 1 primary spermatocyte.
Therefore, the total number of meiotic divisions required to produce 40 zygotes = 40 + 10 = 50.
