Hemophilia is a disease caused by a gene found on the X chromosome. Therefore, it is a sex-linked disease which is caused by the recessive allele. Suppose, a man with hemophilia marries a woman who is homozygous dominant for the trait, what is the chance of having children who are hemophiliacs? (XH = normal; Xh= hemophiliac) * a. 0% b. 75% c. 100% d. 25%
Duchenne muscular dystrophy is sex linked and usually affects only males. Victims of the disease become progressively weaker, starting early in life.a. What is the probability that a woman whose brother has Duchenne’s disease will have an affected child?b. If your mother’s brother (your uncle) had Duchenne’s disease, what is the probability that you have received the allele?c. If your father’s brother had the disease, what is the probability that you have received the allele?
In humans, hemophilia is an X-linked recessive condition characterized by the inability of blood to clot normally. A woman who is a carrier for hemophilia marries a man who has hemophilia. What are the genotypes of the woman and man, respectively? a. xH+xH+, xH+y b. xH+xH xH+y c. xH+xH xHy Od. XHXH, XH+y O e. xHxH xHy
Earlobes can be attached to the face or non-attached. An attached earlobe is a recessive trait. A female with attached earlobes (Il) has a child with a man with non-attached earlobes. He is heterozygous for this trait. Questions: a. What are the possible genotypes of the egg the woman can produce? b. What are the possible genotypes of the sperm the man can produce? c. What is the genotype ratio for the offspring? d. What is the phenotype ratio for the offspring? e. What is the couple's chance of having a child with attached earlobes?
Red–green color blindness is a human X-linked recessive disorder. Jill has normal color vision, but her father is color blind. Jill marries Tom, who also has normal color vision. Jill and Tom have a daughter who has Turner syndrome and is color blind. a. How did the daughter inherit color blindness? b. Did the daughter inherit her X chromosome from Jill or from Tom?
Hemophilia is a disease caused by a recessive allele (h), which is found on the X chromosome, non-hemophilia is (H). A normal man marries a woman that is heterozygous for the trait. Give the genotypes and phenotypes of all possible offspring?
Hemophilia is called "the royal disease" because many European royal families had members with the condition. Hemophilia is a recessive, X-linked disorder. Queen Victoria was unaffected by hemophilia, but was a carrier of the hemophilia gene (X X ). Suppose Queen Victoria's husband, Prince Albert, was affected with hemophilia (X Y). What is the percent probability that a son of Queen Victoria and Prince Albert would be unaffected by hemophilia? probability of unaffected son: What is the percent probability that a daughter or son of Queen Victoria and Prince Albert would be affected by hemophilia? probability of affected child: What is the percent probability Queen Victoria and Prince Albert would have two affected females? probability of two affected females: % % %
