Hemophilia is an X-linked disorder that affects the body’s ability to create blood clots. The allele for normal blood clotting, XH, is dominant over the allele for hemophilia, Xh. An unaffected daughter from the above cross married a man who does not have hemophilia. Determine the probability of their offspring being A daughter with hemophilia A daughter without hemophilia A son with hemophilia A son without hemophilia Express your answer as a phenotypic ratio.

Consider a woman whose brother has hemophilia A but whose parents are healthy. What is the chance that she has inherited the hemophilia allele? What is the chance that the woman will conceive a son with hemophilia?
A form of hemophilia is caused by a sex-linked (X-linked) recessive gene. A phenotypically normal woman whose father had hemophilia marries a man who suffers with hemophilia. What is the probability that their first daughter will have hemophilia?
Hemophilia is a blood disorder which is sex-linked. A woman carrier has children with a normal man. Determine the chances for girls and boys with hemophilia. [Remember that females have the XX genotype and males have the XY genotype. Do not place an allele on the Y chromosome. Example: XN Xn for female; Xn Y for male]
Hemophilia is a sex-linked trait. If you have a man with hemophilia (Genotype XhY) and a female carrier (Genotype XhXh). How many of the offspring would be affected?
Hemophilia is due to a sex-linked gene. It is recessive and found on the X chromosome. A woman who is a carrier for hemophilia marries a normal man. What will be the possible phenotypes of their children? (use the letter “H”)
Hemophilia A, a condition in which blood does not clot properly, is a recessive trait located on the X chromosome (Xh). A woman heterozygous for the trait marries a normal male. What is the probability that this couple will have hemophiliac daughters? What is the probability that this couple will have hemophiliac sons?
Hemophilia is a sex-linked blood clotting disorder (h). A non-hemophilic man marries a woman who carries the recessive hemophilia gene. What is phenotypic ratio of the offspring?
Normal No Spac Hemophilia is a blood clotting disorder that almost exclusively affects males. It is a sex-linked, recessive disorder (X). Using the details below, fill in the Punnett square to determine the percent probability of the couple having a child with hemophilia.

Two forms of hemophilia are determined by genes on the X chromosome in humans. Assume that a phenotypically normal woman whose father had hemophilia is married to a normal man. What is their probability to have a son with hemophilia? (out of all children - not just the sons)
A man with hemophilia has a daughter of normal phenotype. She marries a man who is normal for the trait. The probability of their son to be a hemophiliac is 1/4. Its true or false? Explain.
A mother has AB blood type has a child of AB blood type. What are all the possible genotypes of the father?
D. Sex-linked In humans, hemophilia is a sex-linked trait. Females can be normal, carriers, or have the disease. Males will either have the disease or not (but they won't ever be carriers). 1. Show the cross of a man who has hemophilia with a normal woman. What is the probability that their children will have the disease? H H = female, normal H h X X = female, carrier h xxn XHY X" Y 2. A woman who is a carrier marries a hemophiliac man. Show the cross. What is the probability that their children will have hemophilia? What sex will a child in the family with hemophilia be? 3. A woman who has hemophilia marries a normal man. How many of their children will have hemophilia, and what is their sex? = female, hemophiliac = male, normal = male, hemophiliac
