2. Genetic and Environmental Causes of Variation
3. Explain whether characteristics are inherited,environmental or both.Variation, Inherited, Environmental, Genetic, Factor, Define variation, genetic and environmentalDescribe the factors that cause variationExplain how variation helps a particular species in a changing environmentCritique a claim that a particular characteristic is inherited or environmental
4. Identify and categorise the environmental and genetic characteristics of Kim. Justify your answer.You must write in full sentences.
5. The causes of variationDifferences in the characteristics of different individuals of the same kind may be due to differences in:The genes they have inherited (genetic causes)The conditions in which they have developed (environmental causes)Or a combination of bothGenetic factorsSexual reproduction – leads to genetic variety in the offspring.All offspring (except for identify twins) inherit different characteristics.Asexual reproduction – no genetic variation in the offspring (unless mutations occur).Environmental factorsNutritionTemperatureLightPhysical forces
6. Copy and match the key words to their definitions.GeneticEnvironmentalVariationDifferences between the organisms of the same species. Features caused by the environment in which an organism is exposed to. These could be living factors such as a change in a predator, a food source or a competitor or non-living factors, such as a change in temperature or rainfall.Features determined by an organism’s genetic code. Different genes control the development of different characteristics of an organism. These features can be passed on to an organisms offspring, this can include physical features such as eye colour as well as diseases.
