6. Define species.
- Involves identifying individuals with desired charcteristics
- A group of similar organisms that can breed together to produce fertile offspring
- A measurement of individuals, selected from the population of organisms which are being investigated
7. Asexual reproduction can be increased by..
- Meiosis
- Mutation
- Mutation, Meiosis & fusion of gametes
8. What are the causes of variation?
- Genetic & Environmental
- Selective breeding & The founder effect & Genetic bottlenecks
- Soil conditions & pH
9. Minimising chance..
- Using a large sample size & analysis of the data collected
- Divide the study area, take random coordinates and take samples
10. What are the environmental influences?
- Mutations, meiosis & fusion of gametes
- Climate conditions, soil conditions, pH & food availability
- Asexually reproducing organisms & sexually reproducing organisms
11. 'An influence on all organisms and the way their genes are expressed' is...
- Environmental Factors
- Genetic Factors
12. What is a mutation?
- Sudden changes to the genes (alleles) and chromosomes
- Nuclear division which forms gametes
- Produces harmful toxins within the alleles causing the to distort
13. What is Intraspecific variation?
- Members of the same species also differ from each other
- If one species differs from another
- A group of similar organisms that can breed together to produce fertile offspring
