Inheritance of skin color in humans is dependent not only upon the melanin synthesis genes but also upon a number of other genes. what type of inheritance is exhibited in this case?
a.) polygenic inheritance
b.) multiple alleles
c.) codominance

Part a - which gene to compare? in this exercise, you will use the cytochrome c oxidase i (coi) gene to investigate relationships among salmon species. (this gene encodes a protein that functions in the mitochondrial electron transport chain.) you will compare the coi gene sequences from your salmon test samples to the standard sequences for each salmon species. in order for the coi gene to be useful for distinguishing among the different salmon species, which three statements must be true?
