Topic: Understanding the Relationship Between Heredity and Environment Difficulty Level: Moderate ESSAY 104. Define dizygotic and monozygotic twins. Summarize the genetic and environmental factors that increase the chances of giving birth to both types. Answer: Dizygotic, or fraternal, twins are the most common type of multiple offspring. They result from the release and fertilization of two ova. Genetically, they are no more alike than ordinary siblings. Older maternal age, fertility drugs, and in vitro fertilization are major causes of the dramatic rise in fraternal twinning and other multiple births in industrialized nations over the past several decades. Currently, fraternal twins account for 1 in about every 33 births in the United States. Monozygotic, or identical, twins are created when a zygote that has started to duplicated separates into two clusters of cells that develop into two individuals. The frequency of identical twins is the same around the worldโ€”about 1 in every 350 to 400 births. Environmental influences that prompt monozygotic twinning include temperature changes, variation in oxygen levels, and late fertilization of the ovum. Page Ref: 37โ€“38 105. Explain X-linked inheritance and how it affects both males and females. Answer: When a harmful allele is carried on the X chromosome, X-linked inheritance applies. Males are more likely to be affected because their sex chromosomes do not match. In females, any recessive allele on one X chromosome has a good chance of being suppressed by a dominant allele on the other X. But the Y chromosome is only about one-third as long and therefore lacks many corresponding genes to override those on the X. A well-known example is hemophilia, a disorder in which the blood fails to clot normally. There is a greater likelihood of inheritance by male children whose mothers carry the abnormal allele.

Describe direct and indirect influences on the family, and provide examples of each. Answer: Contemporary researchers view the family as a network of interdependent relationships. Bidirectional influences exist in which the behaviors of each family member affect those of others. These influences operate both directly and indirectly. Kind, patient communication evokes cooperative, harmonious responses, whereas harshness and impatience engender angry, resistive behavior. Each of these reactions, in turn, forges a new link in the interactive chain. In the first instance, a positive message tends to follow; in the second, a negative or avoidant one is likely. When parents are firm but warm, children tend to comply with their requests. And when children cooperate, their parents are likely to be warm and gentle in the future. Furthermore, third parties indirectly influence the family. Interaction between any two family members is affected by others present in the setting. Third parties can serve as supports for or barriers to development. For example, when a marital relationship is warm and considerate, mothers and fathers are more likely to engage in effective coparenting. Effective coparenting, in turn, fosters a positive marital relationship. Page Ref: 45โ€“46 107. Why are so many affluent youths troubled? Answer: Despite their advanced education and great material wealth, affluent parentsโ€”those in prestigious and high-paying occupationsโ€”too often fail to engage in family interaction and parenting that promote favorable development. Compared with better-adjusted counterparts, poorly adjusted affluent young people report less emotional closeness, less supervision, and fewer serious consequences for misbehaviors from their parents, who lead professionally and socially demanding lives. As a group, wealthy parents are nearly as physically and emotionally unavailable to their youngsters as parents coping with serious financial strain. At the same time, these parents often make excessive demands for achievement. Adolescents whose parents value their accomplishments more than their character are more likely to have academic and emotional problems. Page Ref: 48 108. Describe kinship studies, and explain how they are used in the field of developmental science. Answer: Kinship studies compare the characteristics of family members. The most common type of kinship study compares identical twins, who share all their genes, with fraternal twins, who, on average, share only half. If people who are genetically more alike are also more similar in intelligence and personality, then the researcher assumes that heredity plays an important role. Kinship studies are used in the field of developmental science to help determine which traits and behaviors have a genetic link. For example, kinship studies of intelligence provide some of the most controversial findings in the field. Some experts claim a strong genetic influence, whereas others believe that heredity is barely involved. Currently, most kinship findings support a moderate role for heredity. Heritability research also reveals that genetic factors are important in personality. Unlike intelligence, however, heritability of personality does not increase over the lifespan. Page Ref: 53 109. Describe the concept of geneโ€“environment correlation, including passive, evocative, and active types. Define niche-picking. Copyright ยฉ 2018 Laura E. Berk. All Rights Reserved. 33 Test Bank for Berk, Exploring Lifespan Development, 4e Answer: A major problem in trying to separate heredity and environment is that they are often correlated. According to the concept of geneโ€“environment correlation, our genes influence the environments to which we are exposed. At younger ages, two types of geneโ€“environment correlation are common. In passive correlation, the child has no control over the connection. Parents provide environments influenced by their own heredity. For example, musically inclined parents enroll their children in music lessons. In evocative correlation, children evoke responses that are influenced by the childโ€™s heredity, and these responses strengthen the childโ€™s original style. For example, a cooperative, attentive child is likely to receive more patient and sensitive interactions from parents than an inattentive, distractible child. At older ages, active correlation becomes common. Children seek environments that fit with their genetic tendencies. For example, the musically talented child joins the school choir. Niche-picking is the tendency to actively choose environments that complement our heredity. Infants and young children cannot do much nichepicking because adults select environments for them. However, older children, adolescents, and adults are increasingly in charge of their environments. Page Ref: 55 Copyright ยฉ 2018 Laura E. Berk. All Rights Reserved. 34
