Exam 2: Heredity and Environment

It is true that genetic forces sometimes cause people to seek out certain types of environmental situations.

If different members of the family experience quite different environments, this would be reflected in:

In the human body, there are approximately 20 different kinds of cells, which are arranged in different ways to create different tissues and organs.

If a researcher wanted to extract the DNA from a cell, she should look for it in the cell's:

Rene has Down syndrome, which means that she has an extra chromosome on which chromosome pair?

In his professional career, Andy wants to study the risk factors associated with genetic disorders and to provide information and support to parents whose risk factors are high. Andy wants to enter the field called:

If the heritability of a trait is greater than 0 but less than 100%, this would mean that:

To say that genetics and environment interact means that these forces influence each other.

The unique world experienced by each individual is called that person's:

Because there are so many possibilities for how genes can combine in the process of human reproduction, two human parents theoretically could produce hundreds of trillions of genetically unique children.

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:

Current estimates note that the human genome contains about how many genes?

The key to understanding how classical conditioning works is to recognize that it involves the _________ of what will come.

Hemophilia and color blindness are examples of abnormalities associated with genes on the sex chromosomes.

Sometimes in meiosis, genetic material from the mother and father is exchanged between chromosomes. This process is called and the alleles that carry the combination of both parents' genes are called alleles.

Johnson corrects a student who talks about "genetic racial differences" and suggests that a better term to use when talking about genetic differences among defined groups of people would be:

If you were to examine a variety of human body cells under the microscope and look at the number of chromosomes contained in each, you would expect to see 46 chromosomes in all of the following cells EXCEPT:

There are about one million genes in the human genome.

According to the text, the human body contains about how many different types of cells?

The Great Depression is a good example of a nonnormative, history-graded influence.
