3. Is the following autosomal or X-linked? Is it dominant or recessive? Please explain.

B. Now you must make a pedigree chart from the descriptions given. Tell whether it is autosomal or X-linked and

whether it is dominant or recessive. Also, state which type of muscular dystrophy the pedigree could be based off

of the list your teacher has given you. Label the pedigree with the names of the individuals.

Chad and Veronica got married and had Brittany, Kristin, and Harry. It was discovered that Harry had

muscular dystrophy. Brittany married Larry and had Stephan and Stephanie. Stephan also had muscular

dystrophy. Larry’s brother Barry also had muscular dystrophy but neither of their parents had the

disorder.

Draw a pedigree:

Autosomal or X-linked? Dominant or recessive? Name the types of muscular dystrophy this pedigree chart could

represent.
