Meiosis

Question 1

What is the result of Meiosis

Answer 1

4 gametes/ sex cells

Question 2

What are another way to say sex cell.

Answer 2

Haploid, sperm/egg cell, gametes, n.

Question 3

how many stages of Meiosis

Answer 3

8 stages

Question 4

What does Meiosis do.

Answer 4

Increase genetic diversity (allow genes to be exchanged.)

Question 5

Why does organism bother with genetic diversity

Answer 5

leads to advantages or disadvantages for survival

Question 6

Oogensis

Answer 6

-Meiosis in females
-makes eggs
-Only 1 cell turns into an egg (out of the 4)
-The other three called “polar bodies” die off

Question 7

Spermatogenesis

Answer 7

-Meiosis in males
-makes sperm
-all 4 cells survive`

Question 8

What are the 8 stages of Meiosis in order?

Answer 8

Prophase 1
Metaphase 1
Anaphase 1
Telophase 1
Prophase 2
Metaphase 2
Anaphase 2
Telophase 2

Question 9

Homogolous Chromosomes

Answer 9

Chromosomes that are the same size and shape
They have the same genes at the same location
One from male, one from female
TLDR: a pair of somewhat the same Chromatins

Question 10

Tetrads

Answer 10

have four chromaTIDS
Paired sister chromaTINS

Question 11

Crossing over

Answer 11

process when Homologous chromosomes exchange genes
If didn’t occur gametes may be genetically identical
Site of crossing over is called Chiasma

Question 12

Independent assortment

Answer 12

Tetrads randomly arrange along the equator during metaphase 1
