Question 6 1 out of 1 points
Jill's mother was an All-American in the 1500m and qualified for the Olympic team in the marathon. Jill is a freshman
in high school and does not think that she will need to train to become a member of the school's cross- country
team. Jill keeps telling you that her mother was a great runner, so she will also be a great runner. What do you think?
Selected
Answer: Jill might have genes that are correlated with running ability, but she will need to train to become a
great runner.
Answers: She is correct; she will be a great runner no matter what she does.
It is unlikely that Jill even has the genotype for running.
Jill might have genes that are correlated with running ability, but she will need to train to become a
great runner.
There is a specific genotype for running ability, and the odds are good that Jill has inherited it from
her parents.
Question 7 1 out of 1 points
Which statement accurately describes the concept of dominant-recessive inheritance?
Selected
Answer: a pattern of inheritance in which a pair of chromosomes contains one dominant and one recessive
gene, but only the dominant gene is expressed in the phenotype
Answers: a pattern of inheritance in which one gene is expressed and one gene is suppressed
a pattern of inheritance in which a pair of chromosomes contains one dominant and one recessive
gene, but only the recessive gene is expressed in the genotype
a pattern of inheritance in which one gene is dominant and one gene is recessive
a pattern of inheritance in which a pair of chromosomes contains one dominant and one recessive
gene, but only the dominant gene is expressed in the phenotype
Question 8 1 out of 1 points
What type of gene, if it is present, will be expressed in the phenotype?
Selected Answer: dominant gene
Answers: recessive gene
dominant gene
expressed gene
controller gene
Question 9 1 out of 1 points
If an offspring receives a recessive allele for a single-gene trait from both biological parents, the trait will develop in
that offspring.

False
Question 10 1 out of 1 points
Single gene pairs play a crucial role in development. However, it is much more common that developmental
outcomes occur because of the interaction of multiple genes. This is known as _____.
Selected Answer: polygenic inheritance
Answers: inheritability
polygenic inheritance
bimodal inheritance
single dominance
Question 11 1 out of 1 points
Which type of inheritance influences characteristics such as height, weight, skin color, intelligence, personality, and
disease susceptibility?
Selected Answer: polygenetic inheritance
Answers: recessive-dominant inheritance
incomplete dominance
dominant-recessive inheritance
polygenetic inheritance
Question 12 1 out of 1 points
In humans, single genes determine virtually all physical and psychological traits.
Selected Answer: False
Answers: True
False
Question 13 1 out of 1 points
What happens during fertilization that determines the sex of the offspring?
Selected
Answer: The egg or ovum contains the X chromosome and the sperm cells carry either the X or the Y. The sperm
cell that is involved in fertilization determines the sex of the offspring.
Answers:
The egg or ovum contains the X chromosome and the sperm cells carry either the X or the Y. The sperm
cell that is involved in fertilization determines the sex of the offspring.
The sperm cells all carry the X chromosome. The ovum contains both the X and Y, so it is the ovum that
determines the sex of the offspring.
The ovum and sperm cells both carry X chromosomes. The placenta carries both the X and Y, and it
determines the sex of the offspring.
