Exam 3: Genes,evolution,and Environment

For children and adolescents,heritability estimates average around 0.75; that is,about three-quarters of the variance in IQ scores is explainable by genetic differences.

Over the past century and a half,Darwin's ideas have been vehemently rejected by findings in anthropology,botany,and molecular genetics.

Epigenetics refers to:

Roger Bingham wrote: "We live in the space age with a brain from the stone age." This remark reflects the notion that:

Researchers in ________ emphasize the evolutionary mechanisms that might help explain commonalities in areas of human psychology.

When she is teaching a class on "Our human heritage," Prof.Shelbourne,a sociobiologist,is likely to contend that:

Research in the United States indicates that the concentration of lead in black children's blood is 10% to 15% higher than in white children's blood.

PKU (phenylketonuria)is a disorder that:

The four basic chemical elements of DNA are identified by the letters A,B,C,D.

To transform surface structure into deep structure,children must:

The four basic chemical elements of DNA are identified by the letters A,T,C,G.

Even when a trait is highly heritable,it can still be modified by the environment.

Evolutionary biologists often start with an observation about some characteristic and then try to account for it in evolutionary terms.How might they explain the difference in the plumage of male peacocks when compared to that of females?

In the year ________ an international collaboration of researchers called the Human Genome Project and a private company,Celera Genomics,both announced that they had completed a rough draft of a map of the entire human genome.

The A,T,C,and G molecules in DNA code for the synthesis of:

Which of the following is NOT one of the important facts about heritability?

Match these descriptions with the appropriate concept. -A change in gene frequencies within a population over many generations.

The average IQ score for each age group is arbitrarily set at 100.

Those who believe that language and grammar are innate deny that nurture plays any significant role in language development.

The notion that the wealthy and successful are more reproductively fit than other people is called:
