Blood type is a genetically determined trait. Two siblings donate blood and find out their blood types. The brother is Type A and the sister is Type B. Why do the siblings have different blood types?
A. The brother has a different number of blood type genes than his sister.
B. The brother’s blood type gene is on a different chromosome than his sister’s.
C. The brother has different alleles for the blood type gene than his sister does.
D. The brother has a different number of chromosomes than his sister does.
C. The brother has different alleles for the blood type gene than his sister does.
