11.5 Genetic Biodiversity and Genetic Manipulation Quiz

What does genetic biodiversity refer to?

• The rate of mutation in a gene pool

• The genetic similarity between species

• The number of species in a region

• The variety of genes or alleles in an organism

What is a polymorphic locus?

• A type of genetic mutation

• A gene with more than one allele

• A gene with only one allele

• A location where no genetic variation occurs

How is genetic biodiversity calculated?

• Number of polymorphic loci divided by total number of loci

• Total number of genes divided by number of alleles

• Number of alleles divided by number of genes

• Number of monomorphic loci divided by total loci

What does monomorphic loci mean?

• Genes that are frequently mutated

• Genes with only one type of allele

• Genes with no alleles

• Genes with multiple alleles

What can lead to an increase in genetic biodiversity?

• Cloning

• Random mutation and gene flow

• Captive breeding

• Selective breeding

What is gene flow?

• The cloning of genes from one organism to another

• The loss of genes due to selective breeding

• The movement of alleles between populations due to migration

• The transfer of genes from one species to another

What is a genetic bottleneck?

• An increase in allele variety due to natural selection

• A genetic engineering technique

• A decrease in gene pool due to a catastrophic event

• A method of increasing genetic diversity

What effect does selective breeding have on genetic biodiversity?

• Increases the number of alleles

• Decreases the number of alleles

• Increases genetic mutations

• Has no effect on alleles

What is the founder effect?

• The effect of introducing new genes into a population

• A decrease in genetic diversity due to a small gene pool

• A sudden increase in gene variety

• The result of genetic engineering

What role does natural selection play in genetic biodiversity?

• It increases genetic diversity by introducing new alleles

• It decreases genetic diversity by favoring certain alleles

• It has no impact on genetic diversity

• It increases the number of species in an ecosystem
