speciation

• How can a single species evolve into two or more distinct species over time?

  Through reproductive isolation
• What are two factors that can lead to reproductive isolation?

  Geographical location, flowering season
• What is the initial consequence of reproductive isolation on two populations of a species?

  Different gene pools
• What introduces genetic variation within a gene pool?

  Random mutation
• How does natural selection contribute to the divergence of gene pools?

  Different alleles are passed on
• What changes over many generations due to natural selection?

  Allele frequency
• What defines the completion of speciation, where two populations are considered distinct species?

  Inability to produce fertile offspring
• What type of speciation arises from geographical separation?

  Allopatric speciation
• What type of speciation arises from variation in fertilization or courtship behaviour?

  Synaptic selection
