B13 Reproduction

Explain what asexual reproduction is?
The cells divide by mitosis and there is no joining of gametes and so there is no mixing of genetic material. It gives rise to genetically identical offspring (clones).

Explain what sexual reproduction is?
The male sex cell and the female sex cell join to form a zygote which develops into a new individual. Gametes are formed in meiosis. The chromosome number of the original cells halves and then has the right number when joined together.

Explain the difference between the offspring formed from asexual reproduction and form sexual reproduction?
In asexual reproduction the offspring is genetically identical (known as clones) to the parent. In sexual reproduction the offspring inherit genetic information from both parents but won't be identical to either of them.

Name an organism which uses asexual and sexual reproduction?
Bacteria and fungi form from asexual reproduction. Human babies are formed from sexual reproduction.
4 of 5
Describe one advantage and disadvantage for both asexual and sexual reproduction?
Sexual Reproduction: It introduces variation which is key to the long-term survival of a species. It is risky because it relies on two sex cells often from two individuals. Asexual Reproduction: It can be used for growth and repair of worn-out tissue
