# How many mitotic divisions are required to produce 100 eggs?

Contents

Hint: To produce 100 male gametes, 25 meiotic divisions are done, and to produce 100 female gametes, 100 meiotic divisions are done. Hence the total divisions which are essential in humans for the formation of 100 zygotes.

## How many meiotic divisions are required for the production of 100 eggs?

100 male gametes are developed from 100 microspores (from 25 meiotic divisions) and 100 eggs are developed from 100 megaspores (from 100 meiotic division). Hence, number of meiotic divisions necessary for 100 zygotes formation = 25 + 100 = 125.

## How many mitotic divisions are necessary for formation of 100 sperms?

A zygote is diploid (2n) in nature and is formed during the fertilization of male gamete with the female gamete. For 50 zygotes, 50 male and 50 female gametes are required. Therefore, 13 meiotic divisions during spermatogenesis produce 52 sperms and 50 meiotic divisions during oogenesis produces 50 eggs.

## How many meiotic divisions are required to produce?

The meiotic division is involved in the formation of the two types of gametes in an organism, one male gamete, and the other female gamete. The formation of the male gamete requires only one meiotic division which results in four male gametes while the formation of four female gametes requires four meiotic divisions.

## How many divisions are necessary for formation of 80 sperm?

Answer: The number of ‘meiotic divisions’ that are necessary for the production of 80 sperms is 20. Explanation: During the process of spermatogenesis, the haploid sperms are produced by the meiotic division that occurs.

## How many Meiosiss are needed for 50 seeds?

Thus, in order to produce 50 mature ovules, 50 megaspore mother cells will undergo 50 meiotic divisions, one meiosis per megaspore mother cell. This takes the requirement of 50 (in megaspore mother cells) + 13 (in microspore mother cells), i.e., 63 meiotic divisions.

## How many meiotic divisions are required to produce 100 seeds Cyperus?

Thus, in all 200 meiotic divisons are required to produce 100 seeds.

## How many meiotic divisions are required for 76 seeds?

So, total meiotic division required is 375.

## How many meiotic are required to produce 100 Microspores?

The microspore mother cell produces four pollen or microspores by one meiosis which cannot divide further. Hence, for producing 100 microspore/pollen, 100/4 = 25 meiotic divisions are required.

## When a pollen grain is shed at the 3 celled stage which three cells are found?

When a pollen grain is shed at the three celled stage, it contains a vegetative cell and two male gametes.

## How many meiotic divisions are required to produce 240 seeds?

60 microspore mother cells are involved in providing 240 pollen grains. Because each microspore mother cell undergoes meiosis producing four pollen grains (i.e. 60 × 4 = 240). Each pollen grain produces two male gametes of which one undergoes true fertilization of ovule producing seeds.
