Comment: Lisa,
Nice work on this exam! I can tell you studied hard and it paid off. Please look through each question to see what you
missed and let me know if you need any clarification.
Part 1 of 1 - 95.0/ 100.0 Points

A child contains what proportion of their parent’s genetic makeup? 2.5/ 2.5 Points
A. 50:50
B. 33:67
C. 25:75
D. 40:60
Feedback: Correct
Question 2 of 40
What statement describes X-linked traits? Select all that apply. 2.5/ 2.5 Points
