To make a strong argument, the writer or speaker must avoid logical fallacies.
This is because a fallacy is something that is untrue, thus if it was logical your reader might be persuaded against your argument. Basically, as a writer you don't want to contradict yourself and you only want to support one side of an argument.
Hope this helps! :)
B. A supporting detail from common knowledge
Codominance is when both alleles are expressed - one allele is not more dominant than the other.
An example of this is a cow with red and white hair, you can see both colors of hair, not just one.
