In North America, one species of garter snake lives primarily in the water, while another species lives primarily on land. Therefore, they rarely meet and mate. 4. Certain species of plants require hummingbirds to transfer pollen from the male parts of one flower to the female parts of another flower. The shape of the plant flower is compatible only with the one species of hummingbird that transfers its pollen. 5. In the Galapagos Islands, birds called blue-footed boobies will mate only after a specific "dance" is performed where a potential mate displays bright blue feet. 6.

Explanation / Answer

Some closely related species of snails cannot mate because their shells spiral in opposite directions, making it impossible for their reproductive organs to be aligned

Mechanical incompatibility

Although some closely related (but separate) species of salamander can mate with each other to produce offspring, the offspring fail to develop normally and cannot reproduce

Hybrid weakness

In North America, one species of garter snakes live primarily in the water, while another species lives primarily on land. Therefore, they rarely meet and mate.

Habitat isolation

Certain species of plants require hummingbirds to transfer pollen from the male parts of one flower to the female parts of another flower. The shape of the plant flower is compatible only with one species of hummingbird that transfers its pollen

Mechanical incompatibility

In the Galapagos Islands, birds called blue-footed boobies will mate after a specific "dance" is performed where a potential mate displays bright blue feet

Behavioural isolation

Within the open ocean, many species of sea slug release gamete simultaneously, but many eggs of each species cannot be fertilized by the sperm of a different species

Gametic incompatibility

Male fireflies signal to females of the same species by blinking their tail lights at a particular rhythm. Females only respond to signals sent by males of their species

Behavioural isolation
