• XV. Variation in organisms
• 65. Reproduction and variation

• Exam Specifications
• Key Stage 4
• AQA GCSE Science A (4461) Biology
• II. Unit Biology 1b – Evolution and Environment
• 6. Why are individuals of the same species different from each other? What new methods do we have for producing plants and animals with the characteristics we prefer?
• The information that results in plants and animals having similar characteristics to their parents is carried by genes which are passed on in the sex cells (gametes) from which the offspring develop.
• There are two forms of reproduction: sexual reproduction (the joining (fusion) of male and females gametes) and asexual reproduction (no fusion of gametes and only one individual is needed as the parent)
• New plants can be produced quickly and cheaply by taking cuttings from older plants. These new plants are genetically identical to the parent plant.
• AQA GCSE Additional Science (4463) Biology
• II. Biology 2
• 8. Which human characteristics show a simple pattern of inheritance?
• Sexual reproduction gives rise to variation because, when gametes fuse, one of each pair of alleles comes from each parent.

• There are two forms of reproduction: - sexual reproduction, - asexual reproduction.
