- If a couple has six boys, what is the probability that a seventh child will be a girl?Mary has type O blood type . Frank has homozygous type B blood type. Mary had a child with type O blood type. Can frank be the father of this child? Why or why not?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 male individual whose blood type is AB marries fomale whose blood type is A. Is it possible to bear a child whose blood type is 0? Prove your answer by making a Punneft square. L21edmamCystic fibrosis (CF) is an autosomal recessive trait (a). Assume that Emily (who has CF) decides to have children with a man who does not have CF and who is not a carrier of CF. What are their genotypes, and what is the probability that they will have a child who is a carrier for CF?Hemophilia is a sex-linked disorder, where XH = normal gene (no hemophilia) and Xh = hemophilia. A heterozygous female is crossed with an unaffected male. Complete the Punnett square and answer the questions from the parent cross (X#xh mates XHY). XH xh What is the probability of having a child with hemophilia? What is the probability of having a male child with hemophilia? Y What is the probability of having a female child with hemophilia? : xHxh : x*xh : xHy : xhY :: 0% :: 25% :: 50% :: 75% :: 100%
- 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 XhYWhich genotype is homozygous? O aaBb O Aabb O AAbb O AABBBeth and Tom each have a sibling with cystic fibrosis, butneither Beth nor Tom nor any of their parents have thedisease. Calculate the probability that if this couple hasa child, the child will have cystic fibrosis. What would bethe probability if a test revealed that Tom is a carrier butBeth is not? Explain your answers.
- 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?A male with B blood and a female with O blood are expecting a child together. Determine all possible blood types for their offspring. Drawing Punnett squares (2 X 2) as you do this will help.
