A woman with normal blood clotting mates with a man who has hemophilia. Their first child is a boy who has hemophilia. Tests show that the father and son both have the same form of hemophilia, that it is X-linked recessive, and that the boy has normal genetic inheritance. You can predict that if the couple produces more children together, then the odds are that: Select one: O a. All of the children will have hemophilia. O b. Half of the boys and half of the girls will have hemophilia. O c. None of the rest of the children should have hemophilia. O d. Half of the boys and none of the girls will have hemophilia.

An unaffected woman, who is heterozygous for an X-linked allele causing Duchenne muscular dystrophy, has children with a normal man. What are the probabilities of them having an unaffected son or daughter? Short Answer. Please provide your final answer as a fraction

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”)

Boe is normal and his wife is not color-blind, she is a carrier. Which of the following children they can't have? all of them carrier daughter normal daughter color-blind son color-blind daughter

Hemophilia, disease in which the blood lacks a clotting factor, is caused by an X linked recessive gene. Joe doe not have hemophilia and Lucille is heterozygous for the condition.  What is the chance that their MALE child will have hemophilia? (Note: you are calculating the probability for their MALE children only, in other words if they have 1 male child, what is the probability that he will be born with the disease?)     0%     1/4 or 25%     2/4 or 50%     3/4 or 75%     4/4 or 100%

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. Number: Answer Answer Answer Answer Phenotype: Affected female Unaffected female Affected male Unaffected male

A couple can both see red (a sex-linked trait). The allele responsible for red color-blindness is recessive on the X-chromosome. The woman is a carrier for this condition. What are the likely genotypes of this couple? What is the probability of the couple having a daughter who is red colorblind

A healthy couple had their first child affected by cystic fibrosis. Their next three sons were not affected by this disorder. The couple is expecting another child and wishes to know the probability (odds) that this child will be: Not affected if the three brothers are homozygous dominant. Not affected if three unaffected brothers were determined by DNA typing to be carriers. Not affected if she (he) has one affected and five unaffected sisters. Draw pedigree of the family described in c.

A woman with Huntington’s disease (autosomal dominant trait, and she is heterozygous) has children with a healthy man. What proportion of their children will inherit Huntington’s disease?

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 female that is not a carrier mated with an affected male. Which of the following rows identifies the possible genotypes of the offspring?
