To distinguish: Between reciprocity and kin selection in a field study. Also explain, whether an altruistic act is “costly” to an individual who performs it, in the context of natural selection. Introduction: Altruism is an animal behavior that benefits other organism at its own cost. The altruism of an individual will be selected by nature as its sacrificing behavior will lead to an increase in the propagation of its own alleles through kin selection. But altruism is favored only when the benefit gained from the altruistic behavior is more than the fitness cost of the animal showing altruism.

Summary Introduction

To distinguish:

Between reciprocity and kin selection in a field study. Also explain, whether an altruistic act is “costly” to an individual who performs it, in the context of natural selection.

Introduction:

Altruism is an animal behavior that benefits other organism at its own cost. The altruism of an individual will be selected by nature as its sacrificing behavior will lead to an increase in the propagation of its own alleles through kin selection. But altruism is favored only when the benefit gained from the altruistic behavior is more than the fitness cost of the animal showing altruism.

Earlier explanations of altruistic behavior as a form of group selec-tion have been supplanted by Hamilton’s hypothesis of kin selection. What distinguishes kin selection and how does it accord with the no-tion of inclusive fitness, the relative number of an individual’s alleles that pass to the next generation?

Which form of conditioning is used most for behavior modification? Why does this form work better? Why would Classical Conditioning help someone in their daily life functioning? Which form of conditioning would you most likely see in a classroom setting? Create your own examples of each form of conditioning. Be sure to include the following information in your answer. In addressing classical conditioning: Identify UCS, UCR, NS, CS, and CR. Discuss any stimulus generalization that you observed. Discuss any extinction and spontaneous that occurred. In addressing operant conditioning: Identify negative and positive reinforcements and punishments. Label the schedule of reinforcement or punishment.

Types of Selection Match each situation to the type of selection most likely to occur. NOTE: If you want to change your selection, you'll need to delete the one you already chose. After you delete it, the list of choices will pop back up and you can make a different choice. Rabbits with medium colored fur blend into the background, but very light or very dark fur colors are easier for predators to spot. disruptive selection Drab colored guppies are less likely to be eaten by predators, but brightly colored males are preferred by females. sexual selection Butterflies with small wings can easily find hiding places to escape predators. Butterflies with large wings can fly higher and faster to directional selection stabilizing selection escape predators. A species of rodent is vulnerable to cold weather when small, but able to keep warm when large.
