How would you expect the mRNA codons that code for the amino acids that make up hemoglobin to compare between humans and chimpanzees

It would be expected that these codons encode for identical or similar (e. g., equivalent) amino acids.

Explanation:

These hemoglobins represent homologous proteins, this means that they are evolutionarily conserved, have similar sequences and share the same functions

The genetic distance (1.6%) that separates us from the common chimpanzee and the pygmy chimpanzee is roughly twice that between these two species (0.7%). The rest of our DNA is nothing more than normal chimpanzee DNA (and its mRNAs). Thus, our hemoglobin (the protein that carries oxygen and gives our blood its red color), in its normal form, is identical to chimpanzee hemoglobin by each of its 287 units.
