When this happens near land, we see the earth above the two meeting plates rise, forming spectacular mountain ranges. A parallel oceanic trench typically forms just off the shore, as one plate descends deep into the Earthâs core. These convergent boundaries commonly cause volcanoes to form, as old crust melts.
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells â sperm in males, eggs in females. 1  During meiosis one cell divides twice to form four daughter cells. 2  These four daughter cells only have half the number of chromosomes of the parent cell â they are haploid. 3  Meiosis produces our sex cells or gametes (eggs in females and sperm in males).
The meiosis cell cycle has two main stages of division -- Meiosis I and Meiosis II. The end result of meiosis is four haploid daughter cells that each contain different genetic information from each other and the parent cell. Click for more detail.
