Answer:
The correct answer is "each of the MHC genes has a large number of alleles, but each individual only inherits two for each gene".
Explanation:
In normal conditions, an individual has only two different alleles for a given gene: one inherited from his mother and the other from his father. However, this does not mean that among humans, there are only two different alleles for each gene. The major histocompatibility (MHC) genes are a clear example of this, since there are multiple combinations for each MHC class. For instance, there are 40 very similar alleles only for the HLA-B27 subtype.
Eye color and ear shape are inherited.

Species cannot be changed? So my guess is that C. Is the correct answer as it is not a inherited trait.
If that is wrong, then the answer is D. Because I would think body height is influenced by the two parents.
Frameshift mutation affects codons downstream the point of mutation. The previous order of 3 nucleotide- sequences (codons) is consequently changed. This, therefore, changes the protein coded by the mRNA transcribed by the mutated DNA region. Frameshifts are mostly due to insertion or deletion mutations.
