Answer 1

occurs in body cells for growth, repair, asexual reproduction

Question 2

how many divisions does mitosis have?

Answer 2

1 division
- diploid (2n -> 2n)

Question 3

is there crossing over or genetic variation in mitosis?

Answer 3

no

Question 4

what does mitosis result in?

Answer 4

2 identical daughter cells
- clones of the parent cell

Question 5

meiosis

Answer 5

occurs in germ cells for to make gametes for reproduction

Question 6

how many divisions does meiosis have?

Answer 6

2 division
- haploid (2n -> n)

Question 7

what does the meiosis create?

Answer 7

4 genetically unique cells

Question 8

is there genetic variation in meiosis?

Answer 8

yes, crossing over and independent assortment

Question 9

what regulates the cell cycle?

Answer 9

cell cycle checkpoints

Question 10

what promotes mitosis?

Answer 10

M-phase promoting factor

Question 11

how to tell if two alleles are linked?

Answer 11

if there are more parental than recombinant

Question 12

calculating map distance

Answer 12

total recombinant/total # of offspring
MD < 50 = linked

Question 13

what is the independent assortment ratio?

Answer 13

9:3:3:1 for phenotypes
