Match the following
1.Temporal isolation a) Potential mates meet, but choose members of their own species.
2.Ecological isolation b) Individuals of different species do not mate because they are active at different times of the day or in different seasons.
3. Behavioral isolation c) Copulation is attempted, but a transfer of sperm does not take place.
4. Mechanical isolation d) Individuals mate in their preferred habitat, and therefore do not meet individuals of other species with different ecological preferences.
1a,2c,3b,4d
1c,2d,3b.,4a
1a,2b,3c,4d
1b.,2d.,3a.,4c.
As we have already discussed in the Mechanism of Evolution: Reproductive Isolation -
Temporal isolation: Individuals of different species do not mate because they are active at different times of the day or in different seasons.
Ecological isolation: Individuals mate in their preferred habitat, and therefore do not meet individuals of other species with different ecological preferences.
Behavioral isolation: Potential mates meet, but choose members of their own species.
Mechanical isolation: Copulation is attempted, but a transfer of sperm does not take place.
Hence, the correct option is (d).
