Exam 4: Genes, Evolution, and Behaviour

When an individual is the worrying anxious type then psychologically speaking this individual's personality dimension in question is?

Professor Lee wants to study the effects of one specific gene on behaviour. Which of the following procedures would you recommend that she use?

Dr. Jonas is a genetic researcher. She looks at the similarity in personality variables for fraternal versus identical twins. When she reports that identical twins are more similar than fraternal twins, she is really giving you information about

In examining the factors that influence personality traits, the role of genetic similarity has been shown to be equally important compared to the role of the family environment.

You are observing a new species of primates, the Bolos. You note that they are a very peaceful species and do not engage in much competition for mates. Most likely, their mating system is

A domain-specific adaptation is designed to solve a particular problem such as selecting a suitable mate.

The evolutionary perspective might argue that men prefer characteristics in women like clear smooth skin, physical health, and high energy level because they are associated with future reproductive potential and ________.

Though presently there is no quantifiable way to determine the reaction ranges of various intelligence-related traits, research on environmental enrichment programs and adoption studies suggest that the ranges could be

Research has discovered that genetic reaction ranges can be measured directly.

A chromosome is

Within the last 4 million years, the most dramatic growth occurred in the parts of the brain that discourages high-risk behaviours.

Tool use, bipedal locomotion, and social organization placed emphasis on many parts of the body that changed over time in response to all EXCEPT

A heritability coefficient of 0.70 for math ability indicates that 70% of the variation in math ability between individuals is due to genetic factors.

Rob shares _______________ percent of his genes with a real sister and _____ of his genes with a half-sister.

Which of the following specifically refers to a change over time in the frequency with which particular genes occur in an interbreeding population?

Evidence from twin studies has shown that the highest personality trait heritability coefficient has been found openness to experience.

Concordance rates compare behavioural similarity, typically between samples of fraternal or identical twins.

Genes and environment both influence intelligence and personality, but they typically operate independently.

One theory on the evolution of altruism argues that altruism developed because it is a form of long-term cooperation where one individual may help another, but that assistance will be reciprocated at some time in the future. This is called the theory of ________________.

You go to the zoo and observe one panda helping another in an altruistic way. A veterinarian who is about to go check on the pandas sees that you are interested in them and tells you he frequently sees one helping the other out with no obvious benefit to the one doing the helping. If you found out they were related, what theory could best account for their altruistic behaviour?
