Detailed explanation-1: -Gametic incompatibility is when two similar species are unable to reproduce as the sperm cannot successfully fertilize the egg, though the act of mating does occur. This is an example of prezygotic 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 means ‘isolated in time, ’ so this is a mechanism that prevents species from mating because they breed at different times. These differences can be time of day, season, or even different years.

Detailed explanation-4: -Mechanical isolation is a type of reproductive isolation where two species physically cannot undergo fertilization. Mechanical isolation is an example of a prezygotic barrier, where the barrier to reproduction occurs prior to zygote formation.

Detailed explanation-5: -MECHANICAL ISOLATION EXAMPLES The genitalia of a male bushbaby will only fit into the genitalia of a female belonging to the same species. If two bushbabies belonging to different species try to mate, they won’t be able to do so.
