A true-breeding male with dull wings is crossed to a true-breeding female with vibrant wings. All F1 offspring are vibrant. The F1 female offspring are then crossed to true-breeding males with dull wings. All F2 offspring are vibrant. Below are four possible inheritance patterns. Below each one, write either “Possible” or “Not possible”. If you put “Not possible” provide one and only one explanation why it is not possible. A. (6 points) Mendelian inheritance (autosomal recessive) B. (6 points) Mendelian inheritance (autosomal dominant) C. (6 points) Maternal effect D. (6 points) Maternal inheritance
