Reproduction

Question 1

What happens in sexual reproduction?

Answer 1

1) gamete from mother fuses with gamete from father.

2) mixes genetic information from each parent.

3) offspring have different combinations of genes, so show a variety of characteristics.

ADVANATAGE:
- there is variation.

DISADVANTAGE:
- has to find a mate.

Question 2

What happens in asexual reproduction?

Answer 2

1) no fusion of gametes- only one parent.
2) no mixing of genetic information.
3) all offspring have same genes as parent and each other.

ADVANTAGES:
- is faster - one parent needed.
- offspring are genetically identical to each other and the parent.

DISADVANTAGE:
- no variation.

Question 3

How does asexual reproduction produce genetically identical offspring?

Answer 3

This involves mitosis, which produces genetically identical cells.
