Question

Traits that enable an organism to reproduce, without necessarily helping them to survive, are often selected for. Darwin called this idea sexual selection. All BUT ONE is an example of sexual selection in the animal kingdom. A) Larger antler displays in male deer. B) Female flies only breed once per life span. Eliminate C) The male peacock's elaborate tail feathers used to attract the female. D) Male elephant seals fighting over territory and potential female mates.

Answer 2

The answer is B) Female flies only breed once per life span
