Which genetic disorder is characterized by the presence of a zygote having one chromosome
with a normal complement of genes and one chromosome with a missing gene?
Down syndrome
Turner syndrome
Klinefelter syndrome
Cri du chat syndrome

How can an X-linked recessive disease skip generations?
Females are hemizygous for the X chromosome.
Mothers cannot pass X-linked genes to their sons.
The disease can be transmitted through female carriers.
These diseases need only one copy of the gene in females.
The disease can be transmitted through female carriers.
Correct! Since females have two copies of the X chromosome, the mother may provide an
unaffected X to a daughter or son. Furthermore, a daughter may not show signs of the disease
because she has the other X (the only X the father can give to a female) to cancel it out.

Previousquestion
Two teenagers, Charlotte and Hannah, went to ski camp. Charlotte had been vaccinated
against the bacterium meningococcus, but Hannah had not. While they were at camp, both
girls were exposed to meningococcus, but only Hannah became ill.
Hannah had a _______ response to meningococcus, which took longer to produce antibodies
than Charlotte’s _______ response.
Primary, Secondary
Correct! This was the first time her body was exposed to the bacteria.
Response for: undefined
Correct! Charlotte had been exposed to the bacteria when she had the vaccination, thus
building immunization to the bacteria. The vaccine prepares the body to respond to subsequent
encounters with the same bacteria.
Two teenagers, Charlotte and Hannah, went to ski camp. Charlotte had been vaccinated
against the bacterium meningococcus, but Hannah had not. While they were at camp, both
girls were exposed to meningococcus, but only Hannah became ill.

The _________ that phagocytosed bacteria in both teenagers presented antigens
to _________cells, which secreted cytokines.
Macrophages, Helper T
Correct! Macrophages work by eating or phagocytosing bacteria.
Response for: undefined
Correct! Helper T cells are circulating and are activated as the first response to a foreign
pathogen.
Two teenagers, Charlotte and Hannah, went to ski camp. Charlotte had been vaccinated
against the bacterium meningococcus, but Hannah had not. While they were at camp, both
girls were exposed to meningococcus, but only Hannah became ill.
Antibodies against meningococcus directly assisted _________ cells in destroying the
bacteria.
Phagocytic
Correct! Phagocytic cells destroy bacteria through phagocytosis, which is the process of eating
or killing bacteria.
Two teenagers, Charlotte and Hannah, went to ski camp. Charlotte had been vaccinated
against the bacterium meningococcus, but Hannah had not. While they were at camp, both
girls were exposed to meningococcus, but only Hannah became ill.
Respond to the following questions to test your knowledge of the immune response in these
two teenagers.
Charlotte had _________ B and T cells for meningococcus, but Hannah did not.
