Question
ben is a biologist that studies Red Junglefowl, a relative of chickens, on Kauai, an island of Hawaii. Recently, red junglefowl have been mating with feral, or wild, chickens on this island, which has created a hybrid population. One of the biggest differences between chickens and Red Junglefowl is their breeding behaviors. Red Junglefowl females lay only a handful of eggs each year and only in the spring, while domestic chicken can lay many eggs during any season.

Eben collected data on when the hybrid hens were laying their eggs. The graph below shows what he found. Eben wants to know if this hybrid population is evolving to become more similar to domesticated chickens or Red Junglefowl.

Which of the statements most likely explains why this hybrid population has a breeding pattern similar to domesticated chickens?
A.
Breeding only in the spring has a higher survival advantage.
B.
Breeding throughout the whole year has a higher survival advantage.
C.
Breeding in warmer months has a higher survival advantage.
D.
Breeding throughout the who year does not have a survival advantage.

Based on the information provided about the breeding behaviors of Red Junglefowl and domesticated chickens, the most likely statement that explains why the hybrid population has a breeding pattern similar to domesticated chickens is:
B. Breeding throughout the whole year has a higher survival advantage.
This suggests that being able to lay eggs year-round increases reproductive success and survival for the hybrids in their environment, making them more similar to their domesticated chicken relatives.
B. Breeding throughout the whole year has a higher survival advantage.
This suggests that being able to lay eggs year-round increases reproductive success and survival for the hybrids in their environment, making them more similar to their domesticated chicken relatives.
