Speciation Quiz

What is allopatric speciation?

• Formation of a new species due to geographic isolation

• Formation of a new species due to reproductive isolation

• Formation of a new species due to environmental adaptation

• Formation of a new species due to genetic mutation

What is sympatric speciation?

• New species evolving from a single ancestral species in the same geographic region.

• New species evolving from a single ancestral species in the same geographic region but with different genetic traits.

• New species evolving from a single ancestral species in different geographic regions.

• New species evolving from multiple ancestral species in different geographic regions.

What is genetic drift?

• Change in allele frequency in a population over time due to migration of individuals.

• Gradual change in allele frequency in a population over time due to natural selection.

• Sudden change in allele frequency in a population over time due to genetic mutations.

• Random change in allele frequency in a population over time due to chance events.

What is natural selection?

• The process by which certain traits or characteristics become more or less common in a population over time, based on their impact on survival and reproduction.

• The process by which certain traits or characteristics become more or less common in a population over time, based on random chance rather than their impact on survival and reproduction.

• The process by which certain traits or characteristics become more common in a population over time, regardless of their impact on survival and reproduction.

• The process by which certain traits or characteristics become less common in a population over time, based on their impact on survival and reproduction.

How does allopatric speciation occur?

• Random mating within populations

• Ecological competition between populations

• Genetic mutation in populations

• Geographical isolation of populations

What are the factors that can lead to genetic drift?

• Random sampling, small population size, natural disasters, migration, founder effects

• Genetic mutations, large population size, genetic recombination, genetic selection

• Genetic mutations, large population size, genetic recombination, genetic drift

• Random mating, large population size, genetic recombination, genetic selection

What are the different types of natural selection?

• directional selection, stabilizing selection, and disruptive selection

• sexual selection

• artificial selection

• random selection

What is the role of geographic isolation in allopatric speciation?

• Geographic isolation promotes gene flow and prevents genetic divergence.

• Geographic isolation physically separates populations, preventing gene flow and allowing for genetic divergence.

• Geographic isolation leads to the merging of populations and the loss of genetic diversity.

• Geographic isolation has no effect on speciation.
