Answers. 1. The first possibility is that she could have inherited the mutant allele from her mother. The second possibility is that there was a mutation in one of the gametes from her parents, or the mutation occurred in her gametes (not likely as it would have to have occurred 3 times), The third possibility is that a mutation could have occurred in Queen Victoria herself (premeiotic), in the cells that gave rise to her gametes. 2. Yes, two normal parents producing an affected daughter. In this case, we deduce that the mother is a carrier and that a new mutation occurred in the father’s sperm. 3. Von Willebrand’s disease. The gene is most likely to be autosomal. If it was either hemA or hemB, the father would have to show the disease. 4. Alice of Athlone would inherit the hemophilia gene from her father. Therefore she has a 100% chance of being a carrier. Her daughter would get a normal allele from the father and has a 50% chance of getting the hemophilia gene from the mother. 5. Yes, two of her sons are hemophilic. 6. Princess Diana would have to have been a carrier, or else a mutation occurred in a gamete from either Charles or Diana.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
