Calculating genetic biodiversity

Question 1

What is polymorphic gene locus?

Answer 1

• Is a gene locus with more than one allele

Question 2

What is an monophonic gene locus?

Answer 2

• A gene locus with only one allele

Question 3

What is an allele?

Answer 3

• Variation/version of a gene

Question 4

What is a locus?

Answer 4

• The location/position of a gene on a chromosome

Question 5

What is the formula for Calculating genetic biodiversity?

Answer 5

• Proportion of polymorphic gene loci = Number of polymorphic gene loci/ Total number of gene loci

Question 6

What are the steps of Calculating genetic biodiversity?

Answer 6

• First work out the total number of gene loci (add the monophonic and polymorphic value)
• then to get the proportion of the polymorphic value - do the polymorphic value/ the total of gene loci

Question 7

What are the uses of proportion of polymorphic gene loci?

Answer 7

• To compare the genetic biodiversity of re productively isolated populations
• used to monitor genetic biodiversity of
  
  • captive breeding programmes
  • rare breed
  • pedigree animals

Question 8

What can be taken to increase genetic biodiversity, if steps too low?

Answer 8

• transfer mates between zoos

Question 9

What sort of results should we be getting?

Answer 9

• a value that is always less than one

Question 10

What happens the higher the value?

Answer 10

• more genetically diverse population
• greater variety of alleles
• greater variety of phenotype
• selective advantage if environment changes
  more stable population

Question 11

What happens the lower the value ?

Answer 11

• the less genetically bio diverse the population
• not a stable population
  more susceptible to disease/extinction.
