| Question | Answer |
| What Type Of Mutations Can Change The Frequency Of Alleles? | Neutral Mutations |
| What Is Meant By Sympatric specitation? | Speciation brought about by a behavioural or ecological barrier |
| What Is The Definition Of A Species? | Organisms which can interbreed to produce fertile offspring |
| Which Organisms Can Horizontally Transfer Genetic Information Into The Genome Of Eukaryotes? | Viruses and Bacteria |
| What Is Sexual Selection? | The non-random increase in frequency of DNA sequences which increase reproductive success |
| Summarise Natural Selection | Organisms who are better adapted to their environment are more likely to survive to pass on their genes |
| What Is Speciation? | The Formation of a new species brought about by isolation, mutation and selection |
| How Do You Know If Organisms Have Undergone Speciation? | They can no longer interbreed to produce fertile offspring |
| What Is Meant By Gene Pool? | All of the different alleles present in a population |
| What Was The Order Of Evolution Of Life On Earth? | •Last Universal Ancestor •Prokaryotes •Photosynthesis •Eukaryotes •Multi-cellular organisms •Invertebrates •Vertebrates Land Plants |
| What Is Meant By Disruptive Selection? | Favours the extreme versions of a trait and splits population into two groups with their own mean values |
| What Is Meant By Vertical Gene Transfer? | Transfer of genetic information from parents to offspring by sexual or asexual reproduction |
| What Is Evolution? | The changes in organisms over generations as a result of genetic variation |
| Which Organisms Only Transfer Genetic Material By Vertical Gene Transfer? | Eukaryotes |
| What Is Natural Selection? | The non-random increase in frequency of DNA sequences which increase survival |
| What Is Meant By Allopatric Speciation? | Speciation brought about by geographical barriers |
| What Is Meant By Horizontal Gene Transfer? | Transfer of genetic information between individuals |
| Which Type Of Gene Transfer Leads To Rapid Evolutionary Change? | Horizontal gene expression |
| Which Organism Can Transfer Genetic Information By Both Vertical And Horizontal Gene Transfer? | Prokaryotes |
| What Is Meant By Stabilising Selection? | Favours An Intermediate Trait |
| What Is Meant By Directional Selection? | Favours a less common version of a trait until it becomes the most popular |
