101. Doug believes that a person’s intelligence is about half inherited and half dependent on how the person grows up. Doug’s statement best reflects a concept that researchers would call: a. codominance b. a genetic predisposition c. heritability d. a heterozygous trait 10 The extent to which a trait is inherited versus acquired through interactions with the environment defines the concept of: a. heritability b. genetic predisposition c. genetic engineering d. concordance 103. If a particular trait is highly heritable, we would expect to see the highest concordance rates among: a. identical twins b. fraternal twins c. parents and children d. unrelated individuals of the same age 104. If the heritability of a trait was .50, we would expect to see the highest concordance rates among: a. identical twins raised together in the same home b. identical twins raised in different homes c. fraternal twins raised in different homes d. unrelated individuals 105. If the heritability of a trait is greater than 0 but less than 100%, this would mean that: a. heredity was a larger influence on the trait than environment b. environment was a larger influence on the trait than heredity c. both heredity and environment influence the trait d. heredity and environment do not interact in their influence on this trait 106. Which of the following results is consistent with a trait that has a high heritability? a. identical twins are less alike than fraternal twins b. adopted children resemble their biological parents more than their adoptive parents c. unrelated children are as much alike as are brothers and sisters d. brothers are more alike than are sisters 107. Based on the heritability studies cited in the text, the appropriate conclusion to draw is that: a. genes are important in physical development, but not in cognitive and personality development b. genes are important in physical and cognitive development but not in personality development c. genes play only a minor role in human development, regardless of the domain in question d. genes play a significant role in human development of a wide range of human traits and behaviors 108. According to research presented in the text, you should conclude that, under normal circumstances, about what percent of a person’s intelligence is the result of environmental, rather than genetic, factors? a. nearly 100% b. about half c. a small but measurable percent d. virtually zero percent 109. Research suggests that a portion of intelligence is inherited. What percentage of an individual’s intelligence is generally believed to be due to inherited factors? a. 10% or less b. around 50% c. around 75% d. over 90% 110. According to research presented in the text, you should conclude that, under normal circumstances, about what percent of a person’s personality is the result of genetic factors? a. nearly 100% b. about a third to a half c. about 2 to 5% d. virtually zero percent
