When many genes work together to determine a characteristic, there may be a large range of phenotypes that are expressed. Why is this?
a. Because each allele of the genes may be differently structured, leaving a large variety of outcomes.
b. Because there are many combinations of dominant and recessive genes that can lead to various levels of the characteristic being expressed.
c. Because each gene is contributed to by a different chromosome, bringing more phenotypical variety into the characteristic.
d. Because the genes all work to cancel each other out, leaving only one odd gene to express the phenotype.
