Exam 4: Genes, Evolution, and Behaviour

There is evidence that genes play a small role in intelligence, accounting for approximately 25% of group variation in IQ.

While considering behaviour from an evolutionary perspective, it is important to avoid fallacies such as _______.

Evolutionary theory suggests that several personality traits are found in all humans, because they had adaptive functions. These traits are collectively referred to as the

Which of the following concepts asserts that genetically related characteristics that increase the likelihood of survival and reproduction will become more common in a species over time?

The likelihood of two individual share a particular characteristic is often termed?

Researchers have determined that bipolar disorder is more heritable than a major depressive disorder. They found that the more closely related family members are to someone with bipolar disorder, the more likely they are to have bipolar disorder themselves. The correlation is not as strong with major depressive disorders. These types of researchers are referred to as

The heritability coefficient is highest for which of the following human characteristics?

The concept of ____________ states that genes have a predetermined, invariant, and unavoidable effect on traits and behaviour.

Dominance hierarchies are the result of

When an adopted person is more similar to his/her adoptive parents then the importance of ______________ may influence a trait, but if that person is more similar to his/her biological parents, then the importance of _______________ may influence that trait.

When the zygote divides into 2 and each new zygote grows independently then we term this an identical twin?

Early research by Gregor Mendel provided important information leading to which of the following conclusions? Heredity

A fallacy about evolution that your text suggests should be avoided is _______.

While genetic engineering gives humans potential control over heredity and evolutionary processes, there is a key question with respect to the use of genetic engineering?

Children who remain in an impoverished environment sometimes show slight increases in IQ score.

Why does the idea that some members of society are genetically better than others not make sense from an evolutionary perspective?

Dr. Phelps is a genetic engineer. Her research involves cutting strands of DNA for one organism and inserting them into another organism. Her lab is using a

Tool use, bipedal locomotion, and social organization placed the strongest natural selection pressures on which of the following? The _______.

Knowing the level of genetic similarity in family members is important to the study of behavioural genetics because it provides a(n) _______.

Putting your own life in danger for someone else does not make sense in traditional genetic theory. But if we consider the concept of ______ the larger gene pool benefits from your act of altruism
