In humans, hemophilia is a sex-linked condition and normal blood clotting (H) is dominant to the condition of hemophilia (h). A woman with hemophilia marries a normal man. The hat are the probabilities of them having children with hemophilia and their sexes?
A woman with blood type O has a child with blood type O. Her husband, whose blood type is AB is concerned that the child may not be his. Based on what you learned from the inheritance of the ABO blood group system, what conclusions would you make? (Assume that both parents and the child normally produce the H-substance). The husband is right to be concerned because the only possible blood group types expected from both parents are type A or B or O. The husband should not be concerned. Since the child has the exact same blood type of the mother, the child simply inherited the blood type from her mother. The husband is right to be concerned because the only possible blood group types expected from both parents are type A, B, or AB. The husband should not be concerned because he may be a carrier of the O allele. The husband should not be concerned. Since the O allele is dominant, it makes sense that the child should show the O blood type.
A couple are both phenotypically normal but their son suffers from hemophilla, a sex linked recessive disorder. What fraction of their children are likely to suffer from hemophilia. what fraction are likely to be carriers.
A woman with blood type B has a child with blood type O. Her husband, whose blood type is A is concerned that the child may not be his. Based on what you learned from the inheritance of the ABO blood group system, what conclusions would you make? (Assume that both parents and the child normally produce the H-substance). The husband should not be concerned because the A and B blood types from the parents cancel each other in the child to produce an O type. The husband is right to be concerned because neither of the parents have O type blood. The husband is right to be concerned because only the blood types A or B are possible in their child. The husband is right to be concerned because only the blood groups A, B, or AB should be possible in their offspring. The husband should not be concerned because he and his wife may each be carrying an O allele.
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%
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)
Astigmatism and polydactyly are dominant over normal vision and finger traits. Sickle-cell anemia onthe other hand, is an overdominant lethal trait due to its recessive genes (ss). Individuals with this traitdie prematurely. Heterozygotes (Ss), however, have some RBCs that sickle while others remainnormal, thus, not lethal. They are referred to as sickle-trait carriers. A polydactylous, normal-visioned, brown-eyed man with wavy hair has a nonpolydactylous, blue-eyed mother. He proposed marriage to a nonpolydactylous, astigmatic, blue-eyed, and curly-hairedlady whose mother has normal vision. However, the lady is worried about the proposal since sickle-cell anemia has been known to run in both their families. a. Is there a genetic basis for her worry? Explain. b. If it turned out that the lady is a carrier and the man has normal RBC, what would be their COMPLETE genotypes? Male genotype:_________________________________Female genotype: ______________________________ c. Based on their…

Classical hemophilia is a sex-linked disease caused by a recessive gene on the X chromosome. (Hemophilia refers to diseases that cause delays in blood clotting.) If a woman who is acarrierof classical hemophilia has children with a normal male, give the ratios of the possible offspring with respect to classical hemophilia. Be sure to state both the genotypes and the phenotypes of each offspring. For genotypes, use X for a normal X chromosome, Xh for an X chromosome with the hemophilia gene, and Y for a normal Y chromosome. For phenotypes, if the offspring is female, be sure to state if homozygous normal, a carrier, or has the disease. If the offspring is a male, be sure to state if normal or has the disease.
A woman with blood type B has a child with blood type O. Her husband, whose blood type is A is concerned that the child may not be his. Based on what you learned from the inheritance of the ABO blood group system, what conclusions would you make? (Assume that both parents and the child normally produce the H-substance).
Hemophilia is a sex-linked recessive trait. A male hemophiliac and phenotypically normal female have a son with hemophilia. They would like to have one more child. What is the probability of having a child without hemophilia? Explain using a Punnett square. Is it possible for a girl to be born with hemophilia? Explain.
Hemophilia is a sex-linked recessive trait in humans. If a father and a son are both hemophiliacs, but the mother is normal, her genotype must be: XhXh XHXh XHXH XhY
