The kind of genetic variation in happy-face spiders that Dr, Gillespie was studying is called Polymorphism <span>which includes ecology, morphology and the behavior of the happy-face spiders. Polymorphism is a discontinuous genetic variation that results in the occurrence of several different forms or types of individuals among the members of a single species. The happy-face spider exhibits an array of color patterns on the back of its abdomen, sometimes resembles a smiling face. Despite the variation in colors, all of the happy-face spider; have the same anatomical features, interact in the same ways with their environments and with other organisms, they share the same reproductive behaviors and methods of catching insect prey and also freely mate with one another. The study of protein by scientists in the happy-face spiders revealed that different islands had very different levels of variation which means the dispersal between the island is not very common. </span>

c. positive reinforcement; negative reinforcement
d. negative reinforcement; positive reinforcement
e. positive punishment; negative punishment
Answer: c. positive reinforcement; negative reinforcement
Explanation:

In positive reinforcement favorable stimulus is chosen by the subject which made the subject to avail the reward whereas in the negative reinforcement , the aversive stimulus is intended to reduce the undesired behavior by punishment.
