- Why do unrelated children with a disorder such as Down syndrome resemble each other more closely than they do their siblings?A couple who are a carrier of sickle-cell disease with blood type A for the female and type B for the male (assume heterozygosity for blood types). What is the probability that they will have a son with blood type B and is sickle- cell? Please show the solution.What is the labeled part of these figures?
- If two individuals with blood type AB marry, what are the odds that each of their children will have the AB blood type? Draw a Punnett square to answer the question. A father and mother have the following blood types, AO and BB, respectively. Create a Punnett square to determine the possible blood types that their children might have. a. What are the possible blood types of the children? b. Which parent could donate blood to any of the children?Hemophilia is an X-linked disease associated with the inability to produce specific proteins in the blood-clotting pathway. Shown above is a family pedigree tree in which family members afflicted with the disease are shown with filled-in squares (male) or circles (females). A couple is trying to determine the likelihood of passing on the disease to their future children (represented by the ? symbol above) because the hemophilia runs in the woman’s family 4.Assuming that the woman in the couple is a carrier, what is the probability that the couple’s first son will have hemophilia?What is the significance of the P-Q (P-R) interval?
- 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. (Remember that blood types A and B can have 2 different genotypes and you need to take this into account in setting up your Punnett squares.) Possible ABO blood types:______________________ If both of these individuals have Rh+ blood, is there any way they could produce a child with Rh- blood? (Be sure to consider the genotypes for Rh + individuals.) Explain your answer.Jane (mother): Tt XcXc IBi -Taster, Color-blind female, Blood type B John (father): tt XcY IAIB- Non-taster, Color-blind male, Blood type AB Explain whether or not these two parents could possibly produce a normal visioned child who has blood type O? Explain whether or not these two parents could possibly produce a color blind child, who could not taste PTC paper, and has blood type A? What blood types could the children of this couple possibly have? How many phenotypically different "kinds" of children could this couple produce? List a maximum of eight phenotypes. Sorry for asking so many questions but they are related. Please I need your help in a few minutes.If the allelic frequency of A= 0.02 what is the allelic frequency of a =?
- Ronnie is convinced that baby Charlotte must be his daughter. He has heard about something called the “Bombay blood type”, and he is convinced that this phenomenon could explain how he could be Charlotte’s father. Please explain the Bombay blood type and its implications in this SPECIFIC situation, including (i) how it arises and (ii) genes involved, (iii) who would have the Bombay blood type in this scenario, and (iv) could Ronnie be Charlotte’s father, if this was present? Also (v) how could you determine whether the appropriate person actually had the Bombay blood type? Please LABEL the parts of your answer (i), (ii), (iii), (iv), and (v).What is the probability of a child having type AB blood if one of the parents is heterozygous for A blood (Ai) and the other is heterozygous for B blood (Bi)? What other genotypes are possible for children of these parents?Two parents with blood types A and O have a child who has type O blood. What is the probability that their next child will be type A blood group?
