Limitations of the bsc (f24. 4: speciation (f24. 14, dependent on, reproductive isolation, genetic divergence, pop must be isolated (geographically or in some other manner) from one another. Impede mating btwn species or hinder the fertilization of ova if members of a different species attempt to mate: habitat isolation. Live in different habitats: temporal isolation, the species reproduce/mates at different times (day/night, summer/winter, behavioral isolation, mating dance/call doesn"t work, still try to mate, mechanical isolation. This is an example of ___ isolation: temporal, q: is gametic isolation a prezygotic or postizgotic isolating mechanism, prezygotic. 24. 2: speciation can take place with or without geographic separation: speciation can occur in two ways: (f24. 5, allopatric speciation (f24. 6,24. 8, separation, gene flow is interrupted or reduced when a population is divided into two or. Plant species b has a diploid number of: a new species, c, arises as a allopolyploid from a and b.
