Answer:
<h3>Habitat isolation is responsible for causing speciation between the two species of garter snakes.</h3>
Explanation:
- Habitat isolation is a type of isolation in which two species are barred from mating or interbreeding due to the presence of physical barriers between them such as mountains, rivers, etc.
- Habitat isolation only can happen if two species occupy different habitats.
- Example- Gryllus pennsylvanicus prefer to live in those soil which has less water content like in sandy soil & Grylus firmus prefers to live in soil rich in water moisture i.e. loamy soil
