Question

Main difference between mitosis and meiosis in genetics?

Answer 1

@Vocaloid

Answer 2

I'm a little rusty but from what I can remember

mitosis creates cells that are identical to the parent
meiosis creates haploid gametes

Answer 3

ALso differenciat between metaphase I , II Anaphase I , II don't understand the difference between the II

Answer 4

meiosis (only meiosis, not mitosis) undergoes 2 sets of divisions, the first set is prophase I, metaphase I, anaphase I, etc. which separates homologous chromosomes, the second set of division separates chromatids

Answer 5

This is something my professor provided in the lecture and i drew it out iin my notes

Answer 6

is this the anaphase I etc you are taking about in meiosis

Answer 7

like what is this just so I'm clear

Answer 8

yeah, the diagram you posted doesn't show like all the intermediate steps, but yes, after prophase I, metaphase I, anaphase I, and telophase I, you end up with the two cells under "meiosis I" in your diagram

Answer 9

after the second set of division (prophase II, metaphase II, anaphase II, telophase II) you end up with the 4 cells under "meiosis II"

Answer 10

Is this in the prophase II stage?

Answer 11

hm, no, prophase I only

there have to be homologous chromosomes lined up in order for crossing over to ocur, this only happens in prophase I not II
