Answer 1

Involves fusion of male and female gametes

Because 2 parents, offspring contain a mixture of their parents’ genes

Question 2

What does sexual reproduction produce?

Answer 2

Genetically different cells

Question 3

Asexual reproduction

Answer 3

1 parent

No fusion of gametes, no mixing of chromosomes and no genetic variation between parent and offspring

Question 4

What does asexual reproduction produce?

Answer 4

Genetically identical cells

Question 5

Meiosis

Answer 5

Produces cells which half normal number of chromosomes

Question 6

What does meiosis produce?

Answer 6

Gametes

Question 7

What does the cell produced by gamete fusion do?

Answer 7

Replicates itself

Question 8

Advantages of sexual reproduction

Answer 8

Mixture of 2 sets of chromosomes

Variation increases

Better adapted offspring

Can produce offspring with desired characteristics

Question 9

Asexual production advantages

Answer 9

Only needs 1 parent

Uses less energy

Faster than sexual reproduction

Many identical offspring in favourable conditions

Question 10

Examples of organisms that can produce by both methods

Answer 10

Malarial parasites

Fungi

Plants
