Meiosis

Question 1

What is produced by meiosis?

Answer 1

Gametes

Question 2

What is different about cells produced by meiosis

Answer 2

only contain 23 chromosomes

Question 3

What happens before the cell divides?

Answer 3

duplicates genetic information forming two armed chromosomes, after replication the chromosomes arrange themselves into pairs

Question 4

What happens at the first division?

Answer 4

The chromosomes pairs line up in the centre of the cell then are pulled apart so each new cell has 2 copy of chromosomes some of the fathers and mothers go into each new cell

Question 5

What happens in the second division?

Answer 5

Chromosomes line up again in the centre of the cell and the arms of the chromosomes are pulled apart

Question 6

What is the end result in meiosis?

Answer 6

Get 4 gametes with each only a single set of chromosomes, each gamete is genetically different as the chromosomes are shuffled up during meiosis and the gamete only gets half of them

Question 7

After the two gametes fused during fertilisation how does the new cell divide?

Answer 7

Mitosis

Question 8

What happens when the embryo develops?

Answer 8

it differentiates to become specilised
