How many parents do asexual reproduction need?

Answer 2

Only one parent

The cells divide by mitosis

Question 3

Answer 3

Cells divide by mitosis - no joining of special sex cells (gametes) so there is no mixture of genetic information
Therefore no variation

Question 4

What does asexual reproduction give rise to?

Answer 4

Genetically identical offspring known as clones

Only mitosis is involved in asexual reproduction

Question 5

What is the purpose of asexual reproduction?

Answer 5

A zygote

Question 9

How are gametes formed?

Answer 9

Meiosis - chromosome number of the original cell is halved

Question 10

What will the offspring in sexual reproduction have?

Answer 10

Genetic information for both parents - won’t be identical to the parents
Introduces variation

Question 11
