CH11 calculating genetic biodiversity

Question 1

How can genetic biodiversity increase

Answer 1

• mutation in dna creating a new allele
• interbreeding between different populations, gene flow occurs

Question 2

How can genetic biodiversity decrease

Answer 2

• selective breeding
• captive breeding programmes
• natural selection
• genetic bottlenecks
• founder effect

Question 3

Measuring genetic biodiveristy

Answer 3

• measuring polymorphism
• polymorphic genes have more than one allel
