Question
Eben 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.
Figure 1: Red Junglefowl and Feral Hen on Kauai

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.

The statement that most likely 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 option suggests that having the ability to breed year-round allows for more reproductive opportunities and potentially greater survival of the population over time, which aligns with domesticated chickens' reproductive strategy.
**B. Breeding throughout the whole year has a higher survival advantage.**
This option suggests that having the ability to breed year-round allows for more reproductive opportunities and potentially greater survival of the population over time, which aligns with domesticated chickens' reproductive strategy.
