Cystic fibrosis in humans is caused by a recessive allele. A man is known to be a carrier of the cystic fibrosis allele. He marries a phenotypically normal woman. In the general population, the incidence of cystic fibrosis at birth is approximately 1 in 1,700. Assume Hardy-Weinberg proportions. What is the probability that the wife is also a carrier? Answer in decimal number only (three decimal places; example: 0.123). What is the probability that their first child will be affected? Answer in decimal number only (three decimal places; example: 0.123).
A form of hemophilia is caused by a sex-linked (X-linked) recessive gene. A phenotypically normal woman whose father had hemophilia marries a phenotypically normal man with no family history of hemophilia. What is the probability that their first son will have hemophilia? 1/4 1 3/4 0 1/2
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. 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.
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? Select one: a. Female Male XHXH and XHXh XHY and XhY b. Female Male XHXh XHY c. Female Male XHXh XHY and XhY d. Female Male XHXH and XHXh XHY
An individual with a form of red-green color blindness processes a genetically inherited trait that makes it difficult to distinguish red and green color hues. Red-green color blindness tends to skin generations and it is found much more often in men than in women. If a man who was normal and a woman who is a carrier for this form of colorblindness have a child, when the probability that the child will be red-green colorbind is: -0% -25% -50% -75% -100%
Hemophilia is an X-linked recessive trait. The wife is hemophiliac, but the man has normal blood clotting. What is the probability that their SONS will be hemophiliac? 25% 75% 100% 50% 0%
If a female who is a carrier of an X-linked recessive gene for hemophilia mates with a male who does not have hemophilia, what is the chance that their daughter(s) will be a carrier of the gene? O percent 25 percent 50 percent 75 percent
Hemophilia is an X-linked recessive disorder that results in an individual not having a functional gene for a clotting factor and therefore unable to clot blood. A couple has 4 boys. One of the boys has just been diagnosed with hemophilia. What is the probability that all of the other 3 boys will also have hemophilia?
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). X H X H = female, non-hemophilic X H X h = female, carrier X h X h = female, hemophilia X H Y = male, non-hemophilic X h Y= male, hemophiliac a.) Show the cross of a man who has hemophilia with a woman who is a carrier. What is the probability that their children will have the disease? b.) A woman who is a carrier marries a non-hemophilic 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? c.) A woman who has hemophilia marries a non-hemophilic man. How many of their children will have hemophilia, and what is their sex?
A couple each with blood type AB and normal pigmentation have a child with AB blood type and albinism. What is the probability that their next child will have the same phenotype as the first child? Assume that albinism is recessive to normal pigmentations and that this trait assorts independently from the blood group genotypes. Group of answer choices 3/16 9/16 1/8 1/4 1/16
When looking at an X-linked recessive trait, if an affected mother and an unaffected father have a homogametic child, what is the probability that this homogametic child is unaffected? 0.25 1 0 0.5
