Exam 3: Genetics: The Biological Context of Development

Adoptions studies of hostile and antisocial adolescents have found that, compared to controls, they are more likely to have a similarly hostile and antisocial:

In Scarr's dynamic model of gene-environment interactions, the finding that biologically-unrelated siblings raised in the same home grow increasingly dissimilar with age can be explained by the concept of

Body cells duplicate by the chromosomes

Amy has blue eyes. Amy's blue eyes are an example of how her

Genetic disorders may be caused by

Individuals with Down syndrome

Use Gottesman's Limit Setting Model to explain how monozygotic twins reared separately show different phenotypes.

The observable expression of one's genetic makeup is known as the

Use Scarr's Niche-Picking Model to explain how two siblings growing up in the same household are so different.

The process in which cells duplicate, then divide two times, producing four cells, each with 23 single chromosomes is known as

Sickle-cell anemia is characterized by

Mendel's insights into the mechanisms of genetics included all of the following except

Henry Goddard's investigation of approximately 1,000 descendants of Martin Kallikak (a pseudonym), a soldier of the American Revolution, illustrates which of the following research methods?

Twin studies support the influence of genes on
