Chromosomes And Meiosis

Question 1

Gametes have —— the number of chromosomes that body cells have

Answer 1

Half

Question 2

Body cells are also called what?

Answer 2

Somatic cells

Question 3

Germ cells develop into what?

Answer 3

Gametes

Question 4

Where are germ cells located?

Answer 4

Ovaries and testicles

Question 5

What are the sex cells called?

Answer 5

Gametes

Question 6

What’s the difference between body cells and gametes?

Answer 6

Body cells=diploid

Gametes=haploid

Question 7

Diploid cells have —— copies of every chromosome

Answer 7

2 (total number of chromosomes found in body cells)

Question 8

Haploid cells have____copies of every chromosome

Answer 8

1 (making them have half the number of chromosomes found in gametes)

Question 9

How many sex chromosomes and autosomes do gametes have?

Answer 9

Autosomes=22

Sex chromosomes=1

Question 10

Meiosis makes what cells from what cells?

Answer 10

It makes “haploid cells” from “diploid cells”

Question 11

What cells do meiosis occur in?

Answer 11

Sex cells

Question 12

What does meiosis produce?

Answer 12

Gametes

Question 13

How many rounds of division do cells go through in meiosis?

Answer 13

2

Question 14

Meiosis reduces chromosome number and creates_________

Answer 14

Genetic diversity

Question 15

How does meiosis differ from mitosis?

Answer 15

Meiosis has “2” cell divisions whereas mitosis has “1”

In mitosis, homologous chromosomes never pair up

‘Meiosis results in “haploid” cells, mitosis results in “diploid” cells’
