How many meiotic division are necessary for formation of 18 sperm?
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 mitotic division are necessary for formation of sperm?
Answer: There are 5 millions mitotic division required to produce human sperm…
How many meiotic divisions are necessary for the formation of 20 male gametes?
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. So, the five meiotic divisions result in four seeds thus 500 meiotic divisions result in 400 seeds.
How many meiotic divisions are needed for 250 sperms?
Total number of meiotic divisions will be 200+50=250 meiotic divisions.
How many meiotic divisions are required for the formation of 100 sperms?
The meiosis is defined in to four steps, the prophase, anaphase, telophase and metaphase. The cell can produce eggs or sperm only by meiosis process. Hence 25 meiotic divisions are needed to form 100 spermatozoa.
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 meiotic division are necessary for formation of?
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 and mitotic divisions are required for the formation of male gamete?
2 meiotic and 2 mitotic.
How many meiotic and mitotic divisions are required?
Hence, one meiotic division and two mitotic division are required for the formation of fully mature male gametophyte from microspore mother cell in angiosperm.
