Exam 2: Heredity and Environment

The tendency to assume that one's own cultural beliefs are normal and those of others are abnormal is referred to as:

The structure of DNA consists of a long molecule that looks somewhat like a ladder that has been "twisted." The shape of the DNA molecule is referred to as:

Julie and David are excited because Julie has undergone some prenatal testing and today they will see a picture of their unborn baby's chromosomes. Such a picture is called:

Based on the heritability studies cited in the text, the appropriate conclusion to draw is that:

If you were to compare the DNA of any two unrelated people, about what percent of their DNA would be identical?

A single human gene is composed of about how many base pairs?

Most human traits involve polygenic inheritance (multiple genes) rather than a single gene.

DNA refers to:

Mitochondria are the "powerhouses" of a cell.

Suppose that a human female is accidentally exposed to a poison at one of four different points in development. If the effect of the poison is that it interferes with meisosis, at which point in the lifespan would we expect it to have the most disruptive effect?

Viruses used in gene therapy that are capable of penetrating cells and inserting modified DNA into them are called:

Sometimes in the process of meiosis genetic material crosses over from one allele in a chromosome to another. This process results in unique new recombinant alleles.

Down syndrome is an example of an autosomal disorder.

Down syndrome has been shown to be related to which of the following?

The part of the DNA molecule that does not function as genes, but that can influence how genes work is referred to as

Only the most primitive cultures exhibit ethnocentrism, which is the working assumption that one's own beliefs

The primary reason that sex-linked traits are observed more frequently in men than in women is that:

Melissa has a single X chromosome and no Y chromosome, an immature female appearance, and lacks internal reproductive organs. What is the most appropriate diagnosis of her condition?

Sickle-cell anemia is a genetic disorder that is best considered an example of:

Suppose that Shelly's mother has brown eyes and her father has blue eyes. Shelly has brown eyes. In this example we would ______ Shelly's phenotype for eye color and would _________ Shelly's genotype for eye color.
