This week's blogspot requires both an internet entry (to be entered by Thursday 3/18 night as always) and a written response (to be handed in on Friday 3/19). Describe a family as your blog response and draw the corresponding pedigree on unlined paper.
For your Blog entry:
-Identify the trait/disease you are focusing on.
- Classify your trait/disease as autosomal or sex-linked and dominant or recessive
- Describe three generations of the family (use examples from class and your homework to help you or an example from you own family!).
For your Pedigree:
- Draw on unlined paper.
- Be sure all shapes and line are correct and you shade in the appropriate people.
Next week you will be required to draw someone else's family Pedigree so make sure your family description is easy to follow! I encourage you to use something from your own family...if you're unsure about the history of a certain trait, ask your parents for help or give your grandparents a call- I am sure they would love to hear from you! :)
