behavioral isolation gametic isolation habitat isolation mechanical isolation temporal isolation For each description of reproductive isolation, select the option that best describes it. Two species of orchids have different floral anatomy. One species of Drosophilia breed in early morning, another species of Drosophilia breed in the afternoon. Rana aurora (red-legged frog) breeds in fast-moving water. Rana catesbiana (bullfrog) breeds in ponds. Giant clams release sperm and eggs into open water, the gametes recognize one another by molecular markers on the cell surface. gametic isolationExplanation / Answer
1) Two species of orchids have different floral anatomy - Mechanical isolation.
This isolation occurs, when different species are isolated by their genitalia of the males and females, which have different sizes, shapes, or locations.
2) One species of drosophila breed in early morning, another species of drosophila breed in the afternoon - Temporal isolation.
In temporal isolation, populations mate or flower at different seasons or different times of day.
3) Rana aurora breeds in fast moving water. rana catesbiana breeds in ponds - Behavioral isolation.
4) Gaint clams release sperm and eggs into open water, the gametes recognize one another by molecular markers on the cell surface - Gametic Isolation.
In gametic Isolation, gametes fail to attract each other or be recognized such as giant clams release sperm and eggs in open water, and are recognized by molecular markers.
