Question

If we denote a cystic fibrosis gene with a c and a disease-free gene with a C (since the disease is recessive), then only a cc person will actually have the disease. Such persons would ordinarily die before parenting children, but a child can also inherit the disease from two Cc parents (who themselves are

healthylong dash—that

is, have no symptoms but are "carriers" of the disease).

Suppose a child is born to one cystic fibrosis carrier parent and one non-carrier parent. Find the probability that that the child will

have thehave the

diseasedisease.

Answer #1

Cystic fibrosis is an autosomal recessive disorder. Beth and Tom
do not have cystic fibrosis but each have a sibling with cystic
fibrosis. Beth's parents and Tom's mother do not have the disease.,
but Tom's father does. Calculate the probability that if this
couple has a child, the child will NOT have cystic fibrosis.

The Autosomal Recessive disease, Cystic Fibrosis (CF),
runs in Jill’s family. Jill is unaffected. Based on this data,
select which of the following statements could be True?
A.
If Jill’s Paternal Aunt is affected and her Paternal
Grandparents are unaffected. There is a 2/3 probability her father
is a Carrier
B.
In the future, Jill’s parents have another child and
that child has CF. Therefore, her parents have a 100% probability
of being Carriers
C.
Jill could never produce a...

If two normal (disease free) parents each carry the recessive
allele for cystic fibrosis, what is the chance one of their
children could inherit the disease?
Select one:
25% (1 out of 4)
100% (all children)
75% (3 out of 4)
50% (2 out of 4)
No children

Cystic fibrosis (CF) is an autosomal recessive disease. In a
South American country, a study was conducted to test the
hypothesis that cystic fibrosis carriers were less likely to be
affected and die from by tuberculosis (TB) infection. To begin the
quantitative study, researchers needed to identify the number of
individuals in the population that were carriers, knowing the
frequency of the cystic fibrosis allele was 0.1 in the population.
After their analysis, the researchers concluded that there was
evidence...

Sickle-cell anemia is a disease that results when a person has
two copies of a certain recessive gene. People with one copy of the
gene are called carriers. Carriers do not have the disease, but can
pass the gene on to their children. A child born to parents who are
both carriers has probability 0.25 of having sickle-cell anemia. A
medical study samples 18 children in families where both parents
are carriers. What is the probability that four or more...

10. A woman and a man are both carriers for cystic fibrosis.
What will be the probable phenotypes of their
children and the probability of each phenotype
occurring? Pick one.
a. 100% of the children will probably be healthy.
b. 100% of the children will probably have the disease.
c. 50% of the children will probably be healthy, and 50% will
have the disease .
d. 75% of the children will probably be healthy, and 25% will
have the disease.

Cystic fibrosis is an autosomal recessive disorder caused by a
loss-of-function mutation in a chlorine channel, which causes a
thickening of the mucus, leading to respiratory failure. This
disease affects approximately 1 in 1353 newborns in the Republic of
Ireland every year.

in Ireland? Show...
