What kind of genetic variation in happy-face spiders was Dr Gillespie studying?

Dr. Gillespie was studying the genetic variation in happy-face Spiders, specifically focusing on the differences in coloration and patterning of their markings. This variation is believed to be influenced by environmental factors and plays a role in mate selection and camouflage. By examining the genetic basis of these traits, he aimed to understand how such diversity evolves within populations. His research sheds light on the broader implications of natural selection and adaptation in changing environments.
