genetic biodiversity (chapter 11)

Question 1

factors that affect genetic biodiversity

Answer 1

• mutations
• selective breeding
• captive breeding programmes
• rare breeds
• artificial cloning
• natural selection
• the fouder effect
  …

Question 2

calculating biodiversity

Answer 2

• one way in which scientists calculate geetic biodiversity is by measrung polymorphism.
  -polymorhic genes have more than one allele, most gees are monomorphic (only oe allele exists for that gene)
• the greater the polymorhic gene loci, the greater genetic biodiversity of that population.

Question 3

genetic biodiversity

Answer 3

• all members of a species share the same genes, thoguht they may have different versions of these genes (alleles)
• the differences in the alleles among individuals creates genetic biodiversity.
• the more alleles in a population the more genetically biodiveres it is.
• important as thye are more likely to adapt to changes in their enviroment.
