Describe the effect on variation for each
a. asexual reproduction? Creates clones which are identical which creates NO
variation.

Ch. 8 Mitosis/Meiosis
15. What is meiosis used for?
16. What do chromosomes do in meiosis that they DO NOT do in mitosis?
15. What is meiosis used for?
IT IS A REDUCTION DIVISION 2n -> n. IT MAKES
GAMETES FOR REPRODUCTION.
16. What do chromosomes do in meiosis that they DO NOT do in mitosis?
SYNAPSIS: homologous chromosomes seek each other out
and arrange themselves side-by-side.
CROSSING OVER: homologous chromatids exchange
segments. *This increases genetic diversity.
HOMOLOGUES SEPARATE: this is the reduction division.
This, too, increases genetic diversity due to independent
assortment.
