Comparing Mitosis and Meiosis

Slide 001

(1)

Memory Maker!

Mitosis

Makes my “toes”

Slide 002

Meiosis

Makes a new “me”

Overall goal!

Mitosis

Produce identical cells with the

same amount of DNA, to replace dying cells or allow growth.

Slide 002

Meiosis

Produce cells with ½ the

original amount of DNA so that offspring can receive traits

from each parent.

Cells That it Occurs in!

Mitosis

BODY CELLS

(One cell divides once, resulting

in two cells)

Slide 002

Meiosis

REPRODUCTIVE CELLS

(One cell divides twice, resulting in 4

cells)

Effect on DNA!

Mitosis

Amount of DNA is the

same.(Ex: Original Cell = 46

Chromosomes Daughter Cell = 46

Chromosomes)

Slide 002

Meiosis

Amount of DNA is cut in

½.(Ex: Original Cell = 46

Chromosomes Daughter Cells = 23

Chromosomes)
