Transcribed Image Text:3. Reproductive isolation reduces GENE FLOW between populations This means that
each subpopulation evolves separately and can result in a new species. Isolating
mechanisms fall into the following categories. For each category, identify which
example(s) from the chart above matches it.
Reproductive isolation: physiology prevents mating or
producing fertile offspring. Ex. shape or reproductive
organs not compatible
Temporal isolation - timing isolation, individuals mate at
different times of year. Example. frogs that mate in may
versus those that mate in July.
Behavioral isolation - behaviors prevent mating. Ex.
birds recognize mates by songs or dance
