11.5 Calculating Genetic Biodiversity Flashcards
(8 cards)
1
Q
What creates genetic biodiversity?
A
Different alleles for the same gene (gene polymorphism)
2
Q
What is the benefit of having greater genetic biodiversity?
A
Species with it are more likely to be able to adapt to changes in their environment
3
Q
What factors increase genetic biodiversity?
A
- Mutations in the DNA, creating new alleles
- Interbreeding between different populations
4
Q
What factors decrease biodiversity?
A
- Selective breeding
- Captive breeding programmes
- Rare breeds will have low genetic biodiversity
- Natural selection
- Artificial cloning
- Small group of individuals creating a new colony
5
Q
How do we measure genetic biodiversity? (not the equation)
A
By measuring genetic polymorphism
6
Q
What do polymorphic genes have?
A
More than one allele
7
Q
How do you calculate the proportion of polymorphic gene loci?
A
(Number of polymorphic gene loci) / (Total number of loci)
8
Q
The greater the proportion of polymorphic gene loci…
A
The greater the genetic biodiversity
