Mitosis
In which type of reproduction is there no mixing of genetic material?
Asexual
Which type of reproduction produces clones?
Asexual reproduction
What are the advantages of sexual reproduction?
Produces variation in the offspring
If the environment changes variation gives a survival advantage by natural selection
Natural selection can be speeded up by humans in selective breeding to increase food production
What are the advantages of asexual reproduction?
Only one parent needed

Fungi
Many plants
Name the asexual structures released by fungi
