Exam 4: Genes, Evolution, and Behaviour

From a genetic viewpoint, it seems odd that anyone should help another person. But even if that other person is not a family member, altruism makes sense because of the concept of

The heritability coefficient is used to estimate

Natalie has black hair and brown eyes. This is an example of a _______.

Sometimes, as part of the natural selection process, characteristics called "neutral" variations that neither enhance nor hinder survival are passed on.

Across cultures, with respect to gender differences in mate preferences there is ______.

The procedure where scientists use enzymes to cut strands of DNA and then insert the pieces of DNA into other organisms is known as the

Siblings Alisa and Erika were born at the same time but are very different both in terms of looks and personality. We can therefore assume they are ___________ twins.

You are observing a new species from the Amazon rain forest. It would appear that the females spend more time looking after the offspring than the males. According to Trivers' theory regarding mating systems, the likely mating system is

While it appears that species like chimpanzees and humans have evolved mechanisms that support aggressive responses, displays of aggression rely on

You are reading a history textbook and come across the term 'Social Darwinism'. What does this idea refer to?

According to the results of a study by Peggy La Cerra, which of the following men would appear most attractive to a woman?

What is the term used to refer to changes in gene function that occur as a result of environmental factors?

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.

Imagine that you are growing a plant. You are told that, depending on environmental factors (e.g. sunlight, water, etc.), you can expect it to grow between 6 and 10 feet tall. This is most similar to which concept?

Physical or behavioural changes that allow an organism to meet environmental challenges, which in turn increases their survival, are referred to as which of the following?

Every cell in the human body except one type has

What evidence supports a genetic contribution to intelligence, and how much IQ group variation is accounted for?

An adaptation that is designed to solve a particular problem is called a(n) _________.

An adoption study examining the heritability of criminal behaviour found that people whose biological parents and adoptive parents both had criminal records were most likely to be criminals themselves. This study demonstrates

You are trying to interpret the data from a twin study on happiness that was recently published. The researchers measured self-reported happiness across various sets of twins who were either identical or fraternal, and either raised together or apart. If they found that the identical twins raised together were no more similar to each other on a self-reported measure of happiness than the identical twins raised apart, what would that suggest?
