Gametes are Produced by Meiosis

Question 1

What is Meiosis?

Answer 1

Another type of cell division

Question 2

How is it different to miTosis?

Answer 2

It doesn’t produce identical cells

Question 3

Where does meiosis only happen in humans?

Answer 3

In the reproductive organs

Question 4

What does meiosis produce?

Answer 4

Four haploid cells whose chromosomes are NOT identical

Question 5

What happens before the cell starts to divide?

Answer 5

It duplicates its DNA

Question 6

One arm of each chromosome is…

Answer 6

An exact copy of the other arm

Question 7

What happens in the first division of meiosis?

Answer 7

The chromosomes line up in pairs in the centre of the cell

Question 8

First Division - What happens to the pairs?

Answer 8

They are pulled apart, so each new cell only has one copy of each chromosome

Question 9

First Division - What do the father and mother’s chromosomes do?

Answer 9

Go into each new cell

Question 10

First Division -What will each new cell have?

Answer 10

A mixture of the mothers and fathers chromosomes

Question 11

First Division - What does mixing up the genes like this create?

Answer 11

Variation in offspring

Question 12

What happens in the second division of Meiosis?

Answer 12

The chromosomes line up again in the centre of the cell

Question 13

Second Division - What happens to the arms of the chromosomes?

Answer 13

They are pulled apart

Question 14

You get four haploid gametes -

Answer 14

Each only have a single set of chromosomes. The gametes are all genetically different
