In the human pedigree shown below, black filled symbols indicate individuals suffering from a rare genetic disease that has the X-linked recessive mode of inheritance. Empty symbols represent people who do not have the disease. Based on the pedigree, which of the following statements is correct? The disease allele is passed on from the great grandpa of the family on the left. O The disease allele is passed on from the great grandma of the family on the left. O In the third generation, no one is affected, therefore no one carries the disease allele. For the family on the right, no one in the second generation is affected, but at least one of the three individuals must carry the disease allele.

Redgreen color blindness is an X-linked recessive disorder in humans. Your friend is the daughter of a color-blind father. Her mother had normal color vision, but her maternal grandfather was color-blind. What is the probability that your friend is color-blind? (a) 1 (b) (c) (d) (e) 0
In the pedigree attached, the shaded symbols represent people affected with a neurological disorder caused by an X-linked recessive allele. The normal allele is D and the recessive allele is d. What are the genotypes of every person in this pedigree? Please explain in as much detail as possible.

Shown above is a family pedigree tree in which family members afflictedwith the disease Haemophilia are shown with filled-in squares (male) or circles (females). A couple is trying to determine the likelihood of passingon the disease to their future children (represented by the ? symbolabove) because the hemophilia runs in the woman’s family. Turner syndrome is a disease in which an individual is bornwith only a single X chromosome. Suppose the woman in thecouple is a carrier for hemophilia and has a child with Turnersyndrome. Would this child have the disease?
X-linked recessive, carrier mother Unaffected. Carrier mother father X Y XX |Unaffected |Affected I Carrier XY Unaffected Unaffected Carrier daughter Affected son daughter U.S. National Library of Medicine son Color blindedness is a sex-linked trait. If we could see the pedigree chart for several more generations of the family illustrated here, we would expect A) more males to be color blind. B) móre females to be color blind. no females to ever be color blind. D) an equal number of males and females that are color blind.
Attached are three pedigrees. For each trait, considerwhether it is or is not consistent with X-linked recessiveinheritance. In a sentence or two, indicate why or why not.
Duchenne muscular dystrophy is a recessive disorder caused by a rare,loss-of-function allele that is located on the X chromosome in humans. Anunaffected woman (i.e., without disease symptoms) who is heterozygousfor the X-linked allele causing Duchenne muscular dystrophy has childrenwith a man with a functional (non-disease-causing) allele. What is theprobability that this couple will have an unaffected son?
The pedigree below shows inheritance of a particular autosomal (not X-linked) trait across three generations. This trait is controlled by a single gene. Males are shown as squares, females as circles. Shaded shapes indicate the person DOES have the trait, white shapes indicate the person DOES NOT have the trait. This trait is ________, and the genotype of person 10 is ______.
Geneticists are concerned about three different genetic conditions present within their family. Achondroplasia is an autosomal dominant genetic disorder that results in short-limbed dwarfism. (A = achondroplasia allele; a = average height allele). Red-Green Color blindness is an X-linked recessive genetic disorder (Xc = color blindness allele; XC = normal color vision allele). The 7-year-old son has an autosomal recessive form of deafness. (h = deafness allele; H = normal hearing allele.) All three family members were karyotyped, and additional genetic testing was performed to determine the chromosomal location of the genes being studied. The figures below show the karyotypes of the mother and father with respect to the chromosomes containing the three genes mentioned above. Question: The couple’s 7-year-old son has all three of these genetic conditions (achondroplasia, color blindness and deafness). Taking into consideration the genotypes of his parents, what is the complete…

Assume unrelated individuals marrying into the family do not carry the disease, unless there is reason to believe otherwise. What is the chance that IV-3 and IV-4 will have a child with the disease?
