Which type of genetic disease affects males more
frequently than females? - Answer-Sex-Linked recessive.
Since males only have one X and one Y, if the affected
chromosome has the illness, it will be expressed.
In which two conditions are chromosomal abnormalities
the leading known cause? - Answer-Intellectual disability
and fetal miscarriage. Chromosome abnormalities are the
leading known cause of intellectual disability and fetal
miscarriage.
What are three examples of prenatal diagnostic studies? -
Answer-Chorionic villus sampling (CVS), amniocentesis,
and preimplantation genetic testing (PGT) are examples of
prenatal diagnostic studies and are performed in vitro.
CVS is a form of genetic testing that provides genetic
information found in utero and is usually performed
between weeks 11 and 14 of pregnancy. An amniocentesis

is a form of genetic testing that evaluates amniotic fluid
and is usually performed during the second trimester,
between weeks 15 and 20 of pregnancy. PGT is
performed on the embryo prior to implantation.
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? - Answer-Cri du chat syndrome (translated
as "cry of the cat") is caused by a DNA deletion. This term
describes the cry often heard from a baby affected by the
syndrome. Cri du chat syndrome can present as a
microcephalic, low birth-weight baby with a piercing cry.
How can an X-linked recessive disease skip generations?
- Answer-The disease can be transmitted through female
carriers.
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.

Which type of risk is referred to as the ratio of the disease
rate among the entire population to the disease rate in an
unexposed population? - Answer-Relative risk is a ratio of
probability, not an actual occurrence of disease.
What are the empirical risks for most multifactorial
diseases based on? - Answer-Many factors from lifestyle
to genetics affect multifactorial diseases. Observation and
evaluation of each case individually provides the most
thorough and accurate assessment.
What refers to the silenced gene of a gene pair. - Answer-
The imprinted gene is the silent gene of a gene pair.
What is the primary reason that some older adults have
impaired inflammation and wound healing? - Answer-The
underlying chronic illness exists.
A generalized inflammatory response seen in chronic
illness depletes the body's reserves to fight against illness.
Which cells are the body's primary defense against
parasite invasion? - Answer-Eosinophils are the body's
primary defense against parasites.

What Phagocytes bacteria? - Answer-Macrophages work
by eating or phagocytosing bacteria.
What is the first response to a foreign pathogen? -
Answer-Helper T cells
Which characteristic is the most important determinant of
immunogenicity when considering the antigen? - Answer-
Immunogenicity is primarily based on the ability to
recognize something foreign.
How are erythrocytes destroyed when mismatched blood
is administered, causing an ABO incompatibility? -
Answer-The complement pathway is activated in response
to blood incompatibility.
What is the hypersensitivity reaction that causes atopic
dermatitis? - Answer-An immediate (type I)
hypersensitivity reaction causes atopic dermatitis.
Which four infections are considered fungal infections? -
Answer-Infection with a fungus is called mycosis and
