Ib yam li ntawd, tib neeg nug, peb siv mitosis yog dab tsi?

Mitosis yog ib qho tseem ceeb rau peb lub laj thawj tseem ceeb: kev loj hlob thiab kev loj hlob ntawm tes hloov pauv thiab kev loj hlob ntawm asexual

  • Kev loj hlob thiab kev loj hlob. Tom qab meiosis tau tsim ib gamete, thiab qhov no tau fused nrog lwm gamete los tsim ib lub embryo, lub embryo loj hlob siv mitosis.
