(fill in the blanks with the correct number)

-------------------------------------------------Meiosis I ---------Meiosis II -------------------------- ----- Mitosis

chromatids/chromosome:      ____    -->    _____       --> _____ ........................ _____     --> _____

# chromosome sets:               ____n     --> _____n    -->   ____n................... .... _____n   -->  ____n

(1n = haploid)

change in cell #                        _____ --> _____    --> _____ ............................... _____     --> _____

Answer 1

	Mitosis (2n=8)	Meiosis I (2n=8)	Meiosis II (n=4)
	S-phase	End of Mitosis	S-phase	End of Meiosis I	Metaphase II	End of Meiosis II
