AQA spec link: 6.1.1
Relevant chapter: B13 Genetics and reproduction. AQA Biology third edition textbook-Page 196-197.
Specification requires students to know the following;
Students should understand that meiosis leads to non-identical cells being formed while mitosis leads to identical cells being formed. Sexual reproduction involves the joining (fusion) of male and female gametes:
• sperm and egg cells in animals
• pollen and egg cells in flowering plants.
In sexual reproduction there is mixing of genetic information which leads to variety in the offspring. The formation of gametes involves meiosis. Asexual reproduction involves only one parent and no fusion of gametes. There is no mixing of genetic information. This leads to genetically identical offspring (clones). Only mitosis is involved.
Biology only-6.1.3 Advantages of sexual reproduction:
• produces variation in the offspring
• if the environment changes variation gives a survival advantage by natural selection
• natural selection can be speeded up by humans in selective breeding to increase food production.
Advantages of asexual reproduction:
• only one parent needed
• more time and energy efficient as do not need to find a mate
• faster than sexual reproduction
• many identical offspring can be produced when conditions are favourable

Another great resource from you. Thank you, this has saved me a lot of time.
Love your resources saved me lots of time for revision sessions I've been doing keep making more! :)
Good resource, loads of time has gone in to producing it and video links are embedded, although as a result quality is reduced. Will buy some of your other resources. Thank you
