Question

i seriously need help i dont understand this portfolio meiosis ?

Answer 1

Okay, mitosis only undergoes one splitting of the cell (doubling the number of the original) while meiosis undergoes two splits (quadrupling) the number of cells.

Steps of Mitosis:
Interphase: chromosomes becomes condensed and duplicate!
Prophase: chromosomes become visible and centrioles move to opposite sides of the cell, fibers begin to form from the centrioles
Metaphase: chromosomes line up at the "equator" of the cell, known as the metaphase plate (I wonder why :D haha)
Telophase: membrane begins to form and cell begins to split into two
Cytokinesis: Actual split of the cells

Meiosis is very similar to mitosis, except that in meiosis chromosomes "cross over" (chromosomes share their DNA with other chromosomes close by). And meiosis undergoes all off the steps twice. For example, prophase I and prophase II. The other major difference is that at metaphase I, tetrads line up at the metaphase plate, not just a single chromosome. .......Hope this helps!!!!
