10. There are two allelic variants of IGF2. One is 40 kilodaltons (kD) and the second is 50 kD, and both are detectable in the blood. Fred and Mary both only express the 40 kD protein in their blood. They have two sons, Bob and Todd, who both only express the 40 kD protein too. Bob's daughter, Jill, expresses the 50 kD protein in her blood. What can you conclude from these data? a. Fred and Mary must both be heterozygous for the 50 kD / 40 kD variants. b. Fred must be heterozygous for 50 KD / 40 kD variants; Mary's second allele is unknown. c. Mary must be heterozygous for 50 kD / 40 kD variants; Fred may be homozygous for the 40 kD. d. Fred must be heterozygous for 50 kD / 40 kD variants; Mary must be homozygous for the 40 kD. e. Bob is not the biological father of Jill.

![10. There are two allelic variants of IGF2. One is 40 kilodaltons (kD) and the second is 50 kD,
and both are detectable in the blood. Fred and Mary both only express the 40 kD protein in
their blood. They have two sons, Bob and Todd, who both only express the 40 kD protein too.
Bob's daughter, Jill, expresses the 50 kD protein in her blood. What can you conclude from
these data?
a. Fred and Mary must both be heterozygous for the 50 kD / 40 kD variants.
b. Fred must be heterozygous for 50 KD / 40 kD variants; Mary's second allele is
unknown.
c. Mary must be heterozygous for 50 kD / 40 kD variants; Fred may be homozygous for
the 40 kD.
d. Fred must be heterozygous for 50 kD / 40 kD variants; Mary must be homozygous for
