Meiosis and Mitosis

Question 1

What are homologous chromosomes?

Answer 1

Approx. same types of chromosomes.

Question 2

What happens during Prophase 1?

Answer 2

Chromosomes line up and thicken, genes in the same location line up with homologous pairs.

Question 3

What is the purpose of Meiosis?

Answer 3

Meiosis makes gametes.

Question 4

What occurs during Metaphase 1?

Answer 4

Chromosomes are in pairs in the middle.

Question 5

How many chromosomes do sperm and egg cells have?

Answer 5

Sperm cells have 23 chromosomes; egg cells also have 23 chromosomes.

Question 6

What happens during Anaphase 1?

Answer 6

Spindles pull away chromosomes.

Question 7

What is Meiosis considered?

Answer 7

Meiosis is a reduction division.

Question 8

What occurs during Telophase 1?

Answer 8

New nuclei form; 46 chromosomes reduce to 23 chromosomes.

What happens during Cytokinesis?

Answer 9

New cells are formed.

Question 10

What occurs during Prophase 2?

Answer 10

New cells are formed.

Question 11

What happens during Metaphase 2?

Answer 11

Chromosomes are in a single line.

Question 12

What occurs during Anaphase 2?

Answer 12
