Classify the following examples into either prezygotic or postzygotic reproductive isolation mechanisms.
Prezygotic isolation
• female gypsy moths produce pheromones that are not recognized by males of other moth species
• five species of flycatcher birds live in the same area but breed at different times of the year
• Flowers of the black sage are pollinated by one insect and flowers of the white sage are pollinated by a different insect.
• multiple species of coral release their gametes into the water but only those of the same species are able to successfully fuse
postzygotic isolation
• a horse is crossed with a donkey. The resulting offspring is unable to reproduce rith either horses or donkeys
• seeds from hybrid tomatoes are unable to produce more tomatoes
• eggs laid by female drosophila melanogaster that are fertilized by a male D. biarmipes fail to develop into larvae
