biodiversity and simpsons index

What is specie diversity

Number of different species and individuals within each spies of a community

What are the 2 types of species diversity

Species evenness - the relative abundance of each different species within the community

Species richness - the number of different species in a particular area at a particular time.

What is genetic diversity

The variety of genes amongst one species in a population

What is habitat diversity

Range of different habitats

How is genetic diveristy calculated

Genetic diveristy is calculated by examining the olymorphic genes within isolated pop ( e.g where selective breeding is used)

What is the meaning of polymorphic

Genes that has more than one allele (different genetic variants for each trait)

What is monomorphic

Genes that have one allele (rare mutations are less than 1%)

All individuals share exact same genetic variants for that trait

What is the formula for proportion of polymorphic gene loci

Number of polymorphic gene loci / total number of loci (basically total number of genes)

What dos a higher proportion of polymorphic gene loci mean

A higher proportion

Means a larger genetic diversity within the population

What is the 2 n letters in Sampson’s index mean

The N means total number of organisms of all species.

The n total number of organisms of one species.

What should the D value be

Should always be between 0-1

Closer to 0 = lower biodiversity

How do u calculate the Sampson’s index
