Part B Determining genotypes in pedigrees of X-linked
conditions
The pedigree from Part A is shown below. Fill in the most likely
genotypes of the indicated individuals in the pedigree. Note that a
dominant allele followed by an underscore (_) indicates that either
the dominant or the recessive allele may be present at the second
position. Drag one pink label (for condition A, autosomal
recessive) to each pink target. Drag one blue label (for condition
B, X-linked recessive) to each...
this is all that im given
Question 3: (4 points) Consider the following pedigree: O O 1 2 3 4 5 Characterize each of the following modes of inheritance as: Impossible, Possible, or Most likely. Justify your answers. a. Autosomal dominant b. Autosomal recessive X-linked dominant d. X-linked recessive e. Y-linked f. Going with the most likely mode of inheritance .... Assume individual V-1 marries a phenotypically normal male. What is the likelihood that their first child is affected with...
Question 3 5 marks The following pedigree shows a family affected by a rare late-onset disease which is due to a mutation in a maternally imprinted gene. Individuals in generations I and II are all old enough to display the phenotype and all affected individuals are shown. Since this is a late onset disease, individuals in generation III are not yet old enough to display the phenotype, and therefore there are no affected individuals marked in this generation yet. The...
In the family's pedigree shown below, a horizontal pink bar
indicates that an individual is affected with hypercholesterolemia
(high blood cholesterol levels). A vertical blue bar indicates that
an individual is affected with Hunter's syndrome (a lysosomal
storage disease). Individuals I-1 and I-2 have no family history of
Hunter's syndrome, but individuals I-3 and I-4 do.
What is the mode of inheritance for Hunter's syndrome?
For hypercholesterolemia?
a. Autosomal dominant
b. Autosomal recessive
c. X-linked dominant
d. X-linked recessive
e.More...
(Q23-24) The pedigree on left shows the inheritance pattern of one human disease. • O HO 23. Which is the correct description of this disease? A. dominant and autosomal-linked B. dominant and X-chromosomal linked C. recessive and autosomal-linked D. recessive and X-chromosomal linked E. codominant and X chromosomal linked 3 24. What is the probability of an affected child from the marriage between 1 and 2? A. 0% B. 25% C. 50% D. 75% E. 100%
QUESTION 9 5 pe If the characteristic depicted in the pedigree below is rare and subject to complete penetrance, it is likely to be X-linked recessive? 5 6 7 -OOO No, because individuals ll-2 and 11-4 are not affected No, because individuals 111-4 and III-6 are not affected Yes, because individuals III-4 and III-6 are not affected Yes, because only females are affected in generation 11 1. The gene for cystic fibrosis (normal dominant allele CF and abnormal recessive allele...
For each pedigree below determine the most likely mode of
inheritance and label each individual with a genotype. If you know
they have a dominant phenotype, but don’t know the genotype, then
label them with both possibilities. Please use the alleles A and a
for autosomal modes of inheritance and XA, Xa and Ya for any types
of sex-linkage (note: an “a” is only on the Y if the trait is
Y-linked). Modes of inheritance are autosomal dominant, autosomal
recessive,...
a.) Before individual II-2 had an affected
son, this family believed the condition followed a dominant mode of
inheritance. Why does the phenotype of III-1 support a
recessive rather than a dominant mode of inheritance?
b.) Could the mode of inheritance actually be dominant? Explain
using appropriate genetic terms.
c.) In order to better understand the risk of passing this
condition on to additional offspring, individual II-2 sought
genetic counseling which resulted in the drawing of this pedigree.
This action makes...

For each pedigree below determine the most likely mode of
inheritance and label each individual with a genotype. If you know
they have a dominant phenotype, but don’t know the genotype, then
label them with both possibilities. Please use the alleles A and a.
Modes of inheritance for these pedigrees are autosomal dominant or
autosomal recessive. For each pedigree determine if the alternative
mode (not the one you chose) is also possible.
