David Buss believes that _______ not only shapes our physical features but also influences our decision making, aggressive behavior, fears, and mating patterns.

Back 1

evolution

Front 2

According to Baltes, the benefits of evolutionary selection:

Back 2

decrease with age.

Front 3

Albert Bandura would argue that evolutionary psychology focuses too much on _______ and not enough on _______.

Back 3

biology; environment

Front 4

The units of hereditary information that act as a blueprint for cells to reproduce themselves and manufacture the proteins that maintain life are:

Back 4

genes.

Front 5

In the process of meiosis:

Back 5

the cells divide into gametes, which have half the genetic material of the parent cell.

Front 6

Each human gamete has:

Back 6

23 unpaired chromosomes.

Front 7

The typical female chromosome pattern is:

Back 7

XX.

Front 8

Traits that are produced by the interaction between two or more genes are called:

Back 8

polygenic.

Front 9

The complete set of instructions for making an organism is called the:

Back 9

genome.

Front 10

Dominant-recessive gene inheritance involves _______ genes, whereas polygenic inheritance involves _______ genes.

Back 10

2; many

Front 11

Of the following, which is the smallest unit?

Back 11

gene

Front 12

The typical human being begins life with 46:

Back 12

chromosomes.

Front 13

Both of Brian's parents are farsighted, but Brian wears glasses for nearsightedness. Which genetic principle can explain this difference?

Back 13

dominant-recessive genes

Front 14

If you are looking at someone's brown hair, you are observing that person's:

Back 14

phenotype.

Front 15

Amanda was born with Down syndrome. The doctor tells her parents that she will be mentally retarded. If her parents keep her at home without educational or training programs, the doctor predicts that her IQ might go as low as 35, but he predicts it could go as high as 70 if they provide such programs for Amanda.

This variability in Amanda's potential IQ provides an example of the:

Back 15

reaction range for intelligence.

Front 16

The narrow path marking the development of characteristics that appear immune to vast changes in environmental events is called:

Back 16

canalization.

Front 17

Behavioral geneticists believe that behaviors are determined by:

Back 17

a continuous interaction between biological and environmental factors.

Front 18

Twins that develop from a single fertilized egg are called:

Back 18

identical twins.

(monozygotic)

Front 19

Adoption studies are designed to test the different effects of:

Back 19

the home environment and the biological genes.

Front 20

Which genetic disorder is caused by an extra chromosome?

Back 20

Down syndrome

Front 21

List a genetic syndrome that is NOT sex-linked.

Back 21

sickle-cell anemia

Front 22

List genetic syndromes that are NOT sex-linked.

Back 22

a. Klinefelter syndrome
b. Turner syndrome
c. XYY syndrome

Front 23

Mary begs her parents to allow her to take piano lessons. After her first several lessons, it quickly becomes apparent that Mary has a natural talent for music.

This example best illustrates:

Back 23

active genotype-environment correlation.

Front 24

Children who are highly active, easily distracted, and move quickly often elicit adult attempts to quiet them down, punishment for lack of concentration, and angry warnings to slow down.

This describes an example of a(n) _______ genotype-environment interaction.

Back 24

ACTIVE genotype-environment interaction

Front 25

Which prenatal diagnostic test is the least invasive?

Back 25

ultrasound sonography

Front 26

If amniocentesis is performed to determine if a woman's fetus is genetically normal, this will involve:

Back 26

drawing a sample of the fluid that surrounds the baby in the womb.

Front 27

A fertilized ovum is called:

Back 27

a zygote.

Front 28

A thin-walled hollow structure in early embryonic development that contains a cluster of cells called the inner cell mass from which the embryo arises.

The outer layer of cells gives rise to the placenta and other supporting tissues needed for fetal development within the uterus while the inner cell mass cells gives rise to the tissues of the body.

Back 28

blastocyst

Front 29

The developing organism from fertilization to the end of the eighth week:

Back 29

embryo.

Front 30

The period of prenatal development that occurs in the first two weeks after conception is called the _______ period.

Back 30

germinal

Front 31

How does the placenta/umbilical cord life-support system prevent harmful bacteria from invading a fetus?

Back 31

Bacteria are too large to pass through the placenta walls.

Front 32

During which period of prenatal development do cells begin to become different from each other more rapidly and organs begin to form?

Back 32

embryonic period

Front 33

Starts at the moment of conception when the sperm fertilizes the egg and the egg form a zygote.

This then begins to be divided and subdivided into cells and enlarges to form the embryo, which at the end of the second week is rooted in the uterus.

Back 33

zygotic period

Front 34

The human body develops from three layers of cells in the embryo. These layers are the:

Back 34

endoderm, ectoderm, and mesoderm.

Front 35

It is the culmination of the embryo. The fetus is defined as a human being, which rapidly developed after 7 months, leaving the womb in the act of birth.

Back 35

fetal period

Front 36

In general, it is considered that the stages of human development are:

Back 36

1. zygotic period
2. embryonic period
3. fetal period

Front 37

Organs and tissues in an unborn baby are most vulnerable to environmental changes during:

Back 37

organogenesis.
