which of the following is an example of reproductive isolation?
○ male deer with large branching antlers are more likely to mate.
○ one individual from a population of fruit flies from an apple orchard is blown by heavy winds into another orchard where it mates with a different population of fruit flies.
○ one population of frogs mates in the deep water of a pond and another population of frogs mates on the shore of the same pond.
○ a blue lizard washes away from a population of mostly green lizards during a hurricane and ends up on an island containing no other lizards to mate with.

Explanation:

1. Analyze the first option: Male deer with large antlers mating more is about sexual selection, not reproductive isolation.
2. Analyze the second option: Fruit flies from different populations mating after being blown together shows gene flow, not isolation.
3. Analyze the third option: Two frog populations mate in different locations (deep water vs. shore) in the same pond. This is habitat isolation, a type of pre - zygotic reproductive isolation as their mating habitats are different, preventing them from mating with each other.
4. Analyze the fourth option: The blue lizard has no lizards to mate with, but this is due to lack of mates rather than a mechanism that isolates it from its original population for reproduction (it's more of a situation of being alone, not a reproductive isolation mechanism between populations).

Answer:

One population of frogs mates in the deep water of a pond and another population of frogs mates on the shore of the same pond.
