1
Q
What is asexual reproduction?
A
Reproduction involving one parent with genetically identical offspring
2
Q
What is a runner?
A
An offshoot of a plant on which plantlets are produced by asexual reproduction
3
Q
What are the advantages of asexual reproduction?
A
- Only one parent is needed
- It is a more time and energy efficient process as finding a mate is not required
- Many identical offspring can be produced when conditions are favourable
4

What is genetic variation?
A
Inherited differences in organisms
5
Q
What is natural selection?
A
The process by which organisms that are better adapted are more likely to survive and reproduce, which was first described by Darwin
6

What is selective breeding?
A
A process by which humans have chosen organisms to breed together to develop desirable characteristics
7
Q
What is meiosis?
A
Cell division which forms non-identical, haploid gametes
7
