Question

Coiling of shells can vary for snails. Snails that coil to the left cannot mate with snails that coil to the right. This difference leads to reproductive isolation. What kind of reproductive isolation does this example indicate?
a.mechanical isolation
b. postzygotic isolation
c.gametic isolation
d.behavioral isolation

Answer 1

The correction option is A.
Reproductive isolation is divided into two major classes, which are prezygotic and postzygotic isolation. Prezygotic isolation refers to the barriers that are present before the egg can be fertilized while postzygotic isolation refers to those barriers that are present after the egg has been fertilized. Mechanical isolation is a type of prezygotic isolation. Mechanical isolation is a type of reproductive barrier which exist because the male and the female genitalia have different sizes, shapes and locations. The snails that coil to the left and those that coil to the right have the locations of their genitalia in different places.
