Chapter 4.7, Problem 1EG
Did the fact that Prince Albert and Queen Victoria were first cousins have anything to do with the fact that she carried the allele for hemophilia? Why or why not?

Students have asked these similar questions
Queen Victoria had 1 (Leopold) out of four male offspring with hemophilia. What was the probability of this scenario?
Hemophilia is known as "The royal disease" because many of the European royal families had members afflicted with it. A really famous case was Queen Victoria's (1819-1901) descendants who spread the disease across Europe, from Spain to Russia.
You can see the pedigree of Queen Victoria's family here:Hemophilia is an X-linked recessive disease. With the information provided, please answer the following questions:
Fred has blood type AB. His wife Sandra is blood type O. Sandra has baby Joe who is blood type A. Could Fred be the father?
Mr. and Mrs. Smith are concerned because their own blood types are A and B, respectively, but their new son, Richard, is blood type O. Could Richard be the child of these parents?

- I will be adding two questions here because I asked two of the same questions twice by accident earlier. A man and a woman do not have hemophilioa, but the womans father did. (Hemophilia is X-linked recessive). a) What is the probability that they will have a child with hemophilia? b) Is it possible for any of their daughters to be affected? Explain. A cross between a horse homozygous for red hair and a horse homozygous for white hair results in offspring with the coat colour called roan. When you look at the fur of the roan offspring you see both red and white hairs. What type of inheritance best explains this? a) blending inheritance b)codominance c)incomplete codominance d)multiple allelesarrow_forward3) Isabella has blood type O her son also has blood type O. She claims that her friend, Ivan, is the child's father. a) Ivan's blood type is A. Can he be excluded as the father on this evidence alone? b) Does the fact that Ivan's mother has type A blood and his father has type AB blood exclude him from being the parent? c) Does the additional information that Ivan's mother's parents are both AB permit him to be excluded?arrow_forwardJackie is blood type O, her mother is blood type A, and she believes her father is blood type AB. Is she correct? Explainarrow_forward

- A) A woman with type O blood is expecting a child. Her husband is type A and her husband's parents both had type AB blood. What will be their child’s blood type? 2. A)A woman with type O blood is expecting a child. Her husband is type A and her husband's parents both had type AB blood. What will be their child’s blood type? B) A couple has one child with type AB blood.

Type AB blood? O blood?arrow_forwardThe pedigree for Queen Victoria of England, acarrier of hemophilia A, shows the transmission tosome of her descendants, including members ofmany royal families in Europe, such as Russia andSpain, but not Germany.
