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 |
