what type of cell does meiosis produce?
haploid
what does meiosis produce in animals?

what does meiosis produce in plants
spores (pollen)
what does 2 haploid gametes join together to form
diploid zygot
what is meiosis 1
number of chromosomes decreases
what is meiosis 2
identical to mitosis
(nuclei divide again)
what are thr 4 phases of meiosis
pmat
what happens in early prophase
centrioles seperate
forms spindle
chromosomes shorten and become visible
what happens in late prophase
chromatids breaking down at corresponding points
what happens in metaphase
homologus pairs of chromosomes arrange on spindles equator
what happens in anaphase
homologus pairs are seperated
move to seperate poles of the cell
telophase
nuclear membrane reforms around the 2 groups of seperated chromosomes
