Protein synthesis occurs in the cytoplasm, specifically in the ribosomes. Proteins that are meant to be excreted, such as in the pancreas, are produced in the rough endoplasmic reticulum which is a membrane studded with ribosomes. In organs that primarily function to produce and secrete proteins, there will be a larger rough endoplasmic reticulum with more ribosomes.
The fact that they can breed but cannot produce fertile offspring shows that they are different species. T<span>hey may have different characteristics which means they cannot breed </span>successfully, too.
I hope this helps! :-)
