Exam 4: Genes, Evolution, and Behaviour

Carol's parents live in southern Florida, where anoles (small lizards) are common. Every time she visits, Carol removes more anoles from inside her parents' pool cage. There is no way for new anoles to get into the cage, so all the anoles there now are either the original interlopers or their offspring that have inherited the qualities that allowed the original anoles to escape capture. As a result, the anoles that are still inside the cage, including the babies, are very difficult to catch and remove. On a microcosmic level, the increasingly clever anoles in the pool cage are the result of

Neutral variations among characteristics, which may meet future environmental demands, are known as 'evolutionary noise'.

Evolutionary theorists argue that women prefer older men because they are more likely to have

The particular characteristic that a gene controls will be displayed if a gene is ______________.

All of the following are gender differences with regard to important characteristics for dating partners and spouses EXCEPT

Studies comparing the similarity of identical and fraternal twins who are raised together and apart are especially informative because

Scientific advances have enabled genetic researchers to manipulate or alter genes. When this technique is perfected, it could be used to prevent the development of diseases like sickle-cell anemia by keeping abnormal genes from carrying out their preprogrammed function. This scientific intervention is called a ___________________ procedure.

Dr. Erickson studied a number of monozygotic twins and reports that the heritability of friendliness is +1.35. You do not believe him. Why?

The procedure in which an individual gene is altered to prevent it from carrying out its normal function is called the

In the Five Factor Model of personality, neuroticism is defined as negative and hypercritical.

While a large number of human characteristics are under genetic, that influence is not perfect. Genes really determine the ______ for any characteristic.

In the Minnesota Twin Study, genetics accounted for a percentage of the variation among people in personality trait scores. This percentage range was __________.

According to Trivers' theory regarding mating systems, only one of the systems predicts that the females will be larger and stronger than the males. Which one?

Which of the following is a widespread misconception about evolutionary theory? Every human characteristic can be attributed to _________________.

Which of the following would have the highest heritability coefficient?

Sex cells are different from all other cells in the human body because they

As you observe a new species of chimpanzee, you note that they seem to use dominance hierarchies. Thus, we would expect a reduced amount of

The specific genetic makeup of the individual is the person's ______________.

Recombinant DNA procedures refer to the process in which

In a species of birds, a researcher observes little sexual dimorphism in size or strength. This leads the researcher to believe that parental investment is _______________.
