_{^{3. Jumlah kromosom seorang anak sama dengan jumlah kromosom pada orangtua, yaitu 2n (diploid)}}

_{^{4. Sifat sel anak sama dengan sel induk}}

_{^{5. Terjadi pada sel-sel tubuh (sel somatik), misalnya pada jaringan embrional, termasuk ujung akar, ujung batang, lingkaran kambium.}}

_{^{6. Melewati tahap pembelahan, interfase, profase, metafase, anafase, dan telofase, tetapi secara umum tahap ini akan kembali ke tahap semula untuk membentuk siklus sel}}
