Answer 1

Answer:

Hey mate ,

Explanation:

Meiosis 1 take place in 4 steps

1. Prophase - it is divided into 5 phases

1. Leptotene -

in this chromosome is visible under the microscope .

2. Zygotene-

chromosome starts pairing called synapsis with the help to synaptonemal complex. This paired chromosome is called homologous chromosome. and bivalent of chromosome is formed .

3. Pachytene -

longest phase. in this phase crossing over take place between non-sister chromosome.

4. Diplotene -

dissolution of synaptonemal complex, and bivalent seperate these X-shaped structure called chiasmata

5. Diakinesis -

chromosome are fully condensed. And end of diakinesis the nucleolus disappear and nuclear envelop break down .

2. Metaphase 1 :-

Bivalent align to equatorial plate . The microtubules from the pole of the spindle attach to the pair of the homologous chromosome.

3. Anaphase :-

The homologous chromosome seperate while., sister chromatids remains associated at their centromeres.

4 . Telophase :-

Nuclear membrane and nucleolus reapper, cytokinesis follows and this is called as dyad cells .

Hope this will help uh!

Answer 2

Answer:

Explanation:

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.
