Abayomi Reply
differences: occurence... one in somatic n other in germ cells no of daughter cells.. 2 and in meisis 4. genetic recombination... only occurs in meiosis during crossing over no. of chromosomes.. remains same in mitosis n reduced to half in meiosis major phases... similar karyokinesis n cytokinesis
Rayyan
karyokinesis... divided into prophase.. meta.. ana.. and telophase... in meiosis.. further division into meiosis 1 and meiosis11 so phases are named as pro1..meta1..ana1..and telo1
Rayyan
differences among phases.. prophase.. other changes similar.. but diff occur in meiosis where synapsis, crossing over,chiasmata formation and tetrad form metaphase... in mitosis chromosomes align at equatorial plate.. in meiosis homologouy chromosomes align at equatorial plate.
Rayyan
anaphase.. in mitosis chromatids gets separated in meiosis chromosomes gets separated.. meiosis 11 is similar to mitosis except that during interkinesis.. duplication in S phase doesnt occur
