Chapter 10 Study Questions

1. 1. A rare dominant mutation causes a neurological disease that appears late in life in all people that carry the mutation. If a father has this disease, what is the probability that his daughter will also have the disease?
   2. Construct Punnett Squares to accompany the crosses shown in Figure 10.4.2.
   3. Draw reciprocal crosses that would show that the turkey E-gene is on the Z-chromosome.
      Some extra reading and other activities!
   4. Read “The Y chromosome is disappearing – so what will happen to men?” a 2018 article published in The Conversation by Darren Griffin and Peter Ellis from the University of Kent. It provides a discussion about the rate of disappearance of the Y-chromosome in the human genome. Also, take a look at the following animation video on YouTube, Recombination of the Y Chromosome | HHMI BioInteractive Video, which relates to this article.
   5. Visit the HHMI Sex Verification Testing of Athletes interactive, by BioInteractive. Relate this back to crossing over in meiosis (In Recombination of the Y Chromosome | HHMI BioInteractive Video on YouTube).
