There is a woman who is a carrier for hemophilia and marries a man with hemophilia. a) Complete the Punnett Square (it is a google drawing so you will have to double click it to go to the drawing and type in and around the square. Hold the CONTROL (or Command) button and press the PERIOD button to write a superscript/exponent.) b) What are the possible genotypes of the children? c) Could any of their children have hemophilia? If so, would the child be male or female? Explain your reasoning.

1. Construct pedigree charts using the inheritance of hemophilia in figure 92. This is X-linked inheritance so you are required to label XX for females and XY for males. The gene responsible for the trait is represented by the superscript which should be specified in the legend.
y 301 Amelogenesis imperfecta is X-linked dominant. Affected XY individuals have extremely thin enamel on the teeth while XX carriers have grooved teeth from uneven deposition of enamel. If an unaffected XY individual were to produce children with a XX carrier partner, a. what would be the expected chance of a XY child being affected with the disease? b. what would be the expected chance of a XY child being affected with the disease?
4. In this pedigree of another family with hemophilia A. If the woman Il-2 has a son, what is the chance that he is affected? II B. If the woman Il-2 has a daughter, what is the chance 1 2 3 4 III that she is affected? -1 C. If the woman Il-2 has 2 sons, what is the chance that neither will be affected? D. What are the chances that the child of II-4 and Il-5 will be affected?
II. Given the following pedigree below, use Punnett squares for each of the following possibilities: a) X- linked dominant and b) X-linked recessive in order to determine what is the mode of transmission of this trait.
