Does Size Really Matter: Male Guppies Attraction Toward Tiny and Huge Guppy Models

Previous research has tested the sexual selection tendencies of male guppies. We tested if size had any influence on these behaviors. It was hypothesized that the males would be more attracted to the larger female models. The study included huge, tiny, and control models. The time spent on each side was a determining factor for the male’s sexual selection. When the times were averaged, there was no significance in the data. Due to our data, it can be observed that the males did not show any preference for either model size.
