EVOLUTION OF A POPULATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
occurs when two or more populations can interbreed but they only reproduce at different times
A
behavioral isolation
B
geographic isolation
C
temporal isolation
Explanation: 

Detailed explanation-1: -Two species might reproduce at different times of the day or year and thus be unlikely to meet up when seeking mates. This is called temporal isolation.

Detailed explanation-2: -Temporal isolation happens when two or more species reproduce at different times. For example, three species of orchid live in the same rain forest. Each species has flowers that last only one day and must be pollinated on that day to produce seeds.

Detailed explanation-3: -Temporal isolation prevents species from interbreeding due to differences in the timing of mating or fertility, such as having different mating seasons. Behavioral isolation prevents species from interbreeding due to a difference in mating rituals or behaviors.

Detailed explanation-4: -a) Temporal isolation. Individuals of different species do not mate because they are active at different times of day or in different seasons. b) Ecological isolation. Individuals mate in their preferred habitat, and therefore do not meet individuals of other species with different ecological preferences.

Detailed explanation-5: -For example, a peculiar form of temporal isolation has been observed between two closely related species of cicadas of the genus Magicicada in the United States. Sexually mature adults of Magicicada tredecim emerge every 13 years, whereas those of M. septendecim emerge every 17 years.
