Question 1

The heritability coefficient is used to estimate

Accepted Answer

A)  the probability that a person will share a given gene with his or her parents. 
B)  the probability that a person will share a given gene with a sibling. 
C)  the extent to which variation in a group of people can be accounted for by environmental factors. 
D)  the extent to which variation in a group of people can be accounted for by genetic factors. 
E)  none of these;the heritability coefficient does not tell us anything about contributions to a trait/characteristic.

Question 6

Many researchers are interested to know whether intelligence is determined mainly by biological factors or mainly by environmental factors.Studies comparing the IQ of identical vs.fraternal twins consistently show a much higher concordance for the identical twins.Which of the following confounding variables might lead us to overestimate the extent to which intelligence might be attributed to genetic heritability in such studies?

C)  the fraternal twins still share a large amount of biological information 
D)  the fraternal twins were separated at birth 
E)  intelligence cannot be accurately measured

Question 7

Let's say you are studying twins and observe that a particular characteristic occurs very often in both sets of monozygotic twins.We would say that this characteristic has
