Exam 4: Genes, Evolution, and Behaviour

The reaction range principle suggests that genetics sets the upper and lower limits for a trait and _________ indicates where in that range a particular trait will fall.

Which of the following beliefs advocates that the genes of some individuals are better than the genes of other individuals?

The theory that states that we are most likely to help others with whom we share the most genes is known as:

Geneticists distinguish between _________,or an individual's specific genetic makeup and ___________,an individual's observable characteristics that result from genetics.

The observable characteristics produced by a particular genetic endowment are called ___________.

The personality trait that may provide an adaptive advantage as it helps in group survival and the care of children is _____________.

Genotypes are present from conception but phenotypes can be affected by the environment.

Through evolution,larger,more complex brains and more sophisticated mental functions affected competition because of animals' ability to:

All cells in the human body have the same number of chromosomes except for _______________.

While the gene knockout procedure has been shown to result in changes in behaviour,interpretation of the findings of this procedure must be made carefully since:

Researchers who believe in the concept of a reaction range are most likely to argue that intelligence is:

Recombinant DNA procedures have been used to produce human growth hormone that has been used to treat children who are abnormally short.The results of the research examining the impact for these children is that:

Both males and females rate mutual attraction as one of the top qualities they seek in a mate.

An animal researcher inserts into the body of a mouse a genetic substance that is designed to prevent neurons from responding to dopamine.The researcher then observes the mouse to determine the impact of the absence of dopamine on the mouse's behaviour.This researcher has just utilized what is called the:

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

Which type of mating system is most common in chimpanzees?

Carol has average size hands for a woman.Her mother has rather large hands and her father relatively small hands for a man.Carol's sister says Carol has a combination of the large and small hands resulting in Carol's medium hand size.Carol has studied genetics in school and knows this is not true because specific traits are passed on,not _______________ ones.

Individuals who put themselves at risk for survival when helping others are displaying ______.

According to the theory of reciprocal altruism,we help those that share their genes with us.

Though the research by Vernon at the University of Western Ontario and Jang at the University of British Columbia showed that attitudes toward things like reading books and participating in organized sports showed the greatest heritability rates,the researchers cautioned that:
