#Unit 9. Evolution & Diversity of Life Forms
Speciation in ancestor as following way
A- Non-swimming populations separated by a river may gradually diverge because there is no gene flow between them
B- Plants commonly exhibit polyploidy, meaning they contain three or more sets of chromosomes
C- The tendency for two species to diverge in morphology and thus resource use because of competition
Which of the following above condition allowed to which type of speciation?
