In the diversity index equation, what does the variable 'N' represent?
the number of species
the total individuals of all species
the diversity index value

Which of the following is true about species evenness?
(Select all that apply)
more even abundances mean higher species evenness and diversity
it is the total number of different species in a habitat
a higher species evenness indicates lower diversity
it is quantified by taking random samples and counting the species present
|
Which of the following is true about species richness?
(Select all that apply)
it is quantified by taking random samples and counting the number of species present
a higher species richness indicates greater diversity
it is measured by taking samples and counting individuals of each species
it is the similarity in population size of each species

Which of the following is true about the Simpson's diversity index (D)?
it ranges from -1 to 1, with 1 representing maximum diversity
it ranges from -1 to 1, with -1 representing maximum diversity
it ranges from 0 to 1, with 1 representing maximum diversity
it ranges from 0 to 1, with 0 representing maximum diversity
|
Which of the following is true about the proportion of polymorphic loci?
it measures species diversity
a lower proportion of polymorphic loci means greater genetic diversity
a higher proportion of polymorphic loci means greater genetic diversity
it is not related to genetic diversity
|

|
Which of the following can decrease the genetic biodiversity of a population?
(Select all that apply)
selective breeding
the founder effect
gene flow
mutations in the DNA of an organism
|
What does polymorphism refer to?
when a gene locus has multiple alleles
