How is it possible that we are able to identify correlations between phenotype and some patterns of behavior?

Explain the various threats to Internal Validity in detail?

Based on coefficients of relatedness, would a person be more likely to behave altruistically towards a cousin or a niece?

Explain frequency-dependent selection in your own words.

Intrasexual selection favors traits that   enhance direct competition among individuals of the same sex. are attractive to the opposite sex. increase survival. are easily adapted to change.

In Biology of Beauty, Cowley found that contemporaryfemales are attracted to males with broad foreheads and strong chins, and that this effect persisted across different cultures. How did Cowley explain this result? A. This is a trick question- this attraction is culturally relative B. Males compete for access to females by developing these features as a form of male-male competition C. There is no evidence that females really are differentially attracted to males with these features  D. Attraction to males with these features is adaptive for females  because males with these traits are usually sexually mature and have healthy immune systems E. Only some human cultures value these traits as attractive.

What does it mean when a correlation coefficient is negative? Canyou think of examples?

Two male deer compete for access to a female by sparring with their antlers. What type of selection pressure is this?  a Intrasexual  b Intersexual

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.

Now consider the illustration above that shows data on how often white fronted bee eater birds will feed the offspring of other birds as a function of the relatedness to those birds. 100 80 Merops bullockoides Unrelated Cousin (0%) (-12%) Half sib (25%) Full sib (50%) Relationship to nestlings Do these data support the conclusion that altruistic behavior, specifically kin selection, is occurring here? Specifically do the data satisfy Hamilton's rule for altruistic behavior and what specifically in the data would represent the terms C and r in Hamilton's equation?
