Step 1
Meiosis is the reduction division which occurs in sex cells or the gametes. Here the chromosome number gets halved hence it is also called the reduction division.

- "Meiosis, oh meiosis, let me tell you what it means. It's a special kind of cell division with some funny little genes. It starts with a cell splitting in two, just like mitosis would; but from there, things get wild and wacky, and I'll tell you if I could. Instead of dividing once more, the cells each split again; creating four brand new cells, not just two like back then. And here's where the magic happens, with chromosomes all pairing up, then swapping bits of info, a dizzying process that can't be summed up. When all is said and done, those four new cells are not quite the same; they've got half the number of chromosomes, and a whole new genetic game. Meiosis, oh meiosis, it's a puzzle that's so much fun. And if you study it like I have, you'll see how it all gets done!"arrow_forwardWhat would 2n=6 cells in metaphase I of meiosis look like?
