Presentation transcript:

Create a Pedigree and punnet squares for each cross using the information below: Bob and Susan married and had four children (A,B, C, & D.) A, B, &C were boys. Bob was affected with the recessive gene for sickle cell. Sue is a carrier. Each of the children married. A & his wife Pam had 4 girls. Pam was a carrier. B & his wife Jan had 4 boys Jan was affected. C & his wife Sara had 2 boys & 2 girls. D & her husband Rob had no children. Give each child a name. 2. Name all the carriers 3. Who is affected ? 4. Who is not affected?
