12 Questions

What type of speciation describes the process where two populations are geographically separated?

Allopatric speciation

Which type of speciation involves the formation of new species without geographic separation?

Sympatric speciation

What type of speciation involves the formation of new species with some degree of spatial overlap between the ranges of the populations?

Parapatric speciation

What does the term 'gene flow' refer to in the context of speciation?

Exchange of genes between populations

What is the ultimate result of genome-level isolation in the context of speciation?

Limited exchange of genetic material

What is the term for the phenomenon where selection on one part of the genome leads to divergence in other genomic regions through genetic hitchhiking?

Genetic hitchhiking

What is the term for the process where selection on one part of the genome leads to divergence in other genomic regions through genetic hitchhiking?

Genomic hitchhiking

In which type of speciation do two species form without geographic separation?

Sympatric speciation

What is the term for the linked genes that are differentiating away to form separate species?

Islands of speciation

What phenomenon occurs when there is a reduction in diversity, making it seem like there is large divergence between two species?

Sweep occurrence

What is the term for the phenomenon where genes move between species, leading to limited differentiation?

Introgression

What do ABBA/BABA technique and genome comparisons help to determine?

Gene flow between species

Test your understanding of allopatric and sympatric speciation in the context of genomics. This quiz covers the concepts of spatial isolation, gene flow, and taxonomic units related to speciation.
