- 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?
- Construct Punnett Squares to accompany the crosses shown in Figure 10.4.2.
- Draw reciprocal crosses that would show that the turkey E-gene is on the Z-chromosome.
Some extra reading and other activities! - 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.
- 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).
