text: another meiosis question, plz help!? okay another biology question from me :) i think im starting to get meiois, in meiosis do u end up with 4 haploid cells, with 23 chromosomes.  and in meiois i you end up with 2 cells which then divide again in meiosis ii??  and one other question- what are the benefits from sexual reproduction from meiosis that does not occur in asexual repro. thanks meiosis takes place in two stages: meiosis 1 and meiosis 2. at the end of meiosis 1, you have two haploid cells with double stranded chromosomes. at the end of meiosis 2, you have four haploid cells with single stranded chromosomes.  crossing over- the stage of meiosis that allows for genetic variability- occurs when the chromatids form tetrads during prophase 1 of meiosis.  this is the only stage that this is able to take place.  sexual reproduction has the benefit of genetic variability.  the coding that will most help the offspring is passed on more frequently than the coding that would give it no selective advantage. asexual reproduction makes exact copies- it would take longer for the organism to adapt to a change in the environment, as it would have to mutate.  this could be very bad for the organism, as the species may die off before the mutation in the genes takes place.
