Question

Explain process of Meiosis

Answer 1

Meiosis is thw process of cell division that happens when half of parent's chromosomes are divided so that both parents gives the same amount of chromosome they each has to their offspring

Answer 2

Here is the answer .. 

Meiosis 


1. There are two stages of Meiosis.
Meiosis I and Meiosis II.

2. By meiosis , from one diploid cell, four haploid cells are formed. 

3. In meiosis, crossing over between the non - sister chromatids of homologous chromosomes occur.
This results in generic recombination.

4. The four daughter cells formed after completion of meiosis are genetically recombined and not exactly alike and also not exactly similar to their parents cells.

Meiosis I 

1. Homologous chromosomes undergo crossing over and hence there is generic recombination.

2. The homologous chromosomes are divided into two groups and from these , two haploid cells are formed.

3. Prophase I of meiosis is lengthy phase which is subdivided into 5 phases , viz. Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis. During Pachytene , crossing over takes place.

Meiosis II 


1. Meiosis II is similar to Mitosis that is mitotic division.

2. The two haploid cells that are produced in meiosis II now undergoes further division forming four haploid cells.
