Exam 2: Heredity and Environment

Protecting the body from disease is the primary function of this type of protein:

Sperm and egg cells are called:

Learning through the method of "successive approximation" is at the heart of the concept called:

Operant conditioning is especially likely to be involved in the development of:

Which chromosomal pair determines the sex of an individual?

An example of a trait that results from incomplete dominance is ________; a trait that results from codominant alleles is __________:

Individuals with this syndrome have a functional X chromosome, but either a missing or inactive second X chromosome.

If it were possible to know exactly what genetic information was contained in an individual's genes, would the field of behavioral genetics have any usefulness?

Which of the following types of information would be of LEAST interest to a genetic counselor?

The field of behavior genetics relies most heavily on data gathered from:

When applied behavior analysis programs involve a slow, progressive set of expectations that become more demanding over time, this is called shaping.

Suppose that hair color is a single-gene trait and that dark hair is dominant and blonde hair is recessive. Also, suppose that Terry's mother has dark hair and his father has blonde hair. If Terry has blonde hair, we would ______ Terry's phenotype for hair color and would ________ Terry's genotype for hair color.

Suppose Sandra has difficulty in concentrating while doing her homework. She decides to reward herself for reading 5 minutes without letting her mind wander. After a week of this, she decides to reward herself only when she reads for 10 minutes without distraction. Finally, she is able to concentrate for 15 minutes at a time without distraction. Sandra's ability to improve her study behavior is best considered an example of:

According to research presented in the text, the genetic locations that are responsible for determining a person's race:

Classical conditioning is most likely to be involved in which of the involving situations?

If we know that a disease results from a sex-linked recessive trait, we would expect that it would:

Which recessive genetic disorder occurs primarily among people of European Ashkenazi Jewish ancestry, resulting in early death in those children afflicted with it?

Workers in Dr. Garcia's lab first obtain tumor cells from patients with cancer. They then remove the DNA from the tumor cell nuclei and use enzymes to segment the DNA strands into sections. Finally, they insert the DNA sections in which they are interested into "host" bacteria cells, where the DNA can be reproduced for later use. Dr. Garcia's lab is engaged in work involving:

Operant conditioning is especially likely to be involved in the development of:
