Answer 1

The variety of living organisms in an area

Question 2

Define the term ‘species diversity’.

Answer 2

The number of different species and the abundance of each species in an area.

Question 3

Define the term ‘genetic diversity’.

Answer 3

The variation of alleles within a species.

Question 4

Answer 4

A species that is unique to a single place and is not found anywhere else.

Question 5

Define the term ‘species richness’.

Answer 5

The number of different species in an area.

Question 6

What is the formula for heterozygosity index

Answer 6

H = number of heterozygotes/number of individuals in the population

Question 7

What is the formula for diversity index?

Answer 7

D = N(N-1)/sum of n(n-1)

Question 8

How does genetic diversity occur?

Answer 8

• Individuals in a species vary because they have different alleles
• The greater the variety of alleles, the greater the genetic diversity of a species

Question 9

Define the term ‘gene pool’.

Answer 9

The complete set of alleles in a species

Question 10

What does the diversity index calculate?

Answer 10

The biodiversity of a population, taking into account the number of species and the abundance of each species.
