2.6 Concepts of Species and Speciation (Part 2: mechanisms of speciation) Flashcards
What are the (2) mechanisms of speciation?
Allopatric, sympatric
What mechanism of speciation is derived from the greek words for “other” and “homeland”?
Allopatric - allos patra
What mechanism of speciation is derived from the greek words for “together” and “homeland?
Sympatric - syn patra
What mechanism of speciation happens when two groups are separated into two species by geographic barriers, preventing gene flow?
Allopatric speciation
What mechanism of speciation happens when two groups separate into two species while living in the same geographical area?
Sympatric speciation
What is the condition of having EXTRA SETS OF CHROMOSOMES as a result of sympatric speciation?
polyploidy
What speciation happens when the genetic pool of two populations differ after years of separation, resulting into different species?
Allopatric speciation
What speciation happens when members of a species do not mate with other species due to mate choice and preference?
Sympatric speciation
