1. Give four specific counter examples for why each of the following definitions for a gene are incorrect. For each definition, there may be several possible counter examples. For full credit, each counter example should be distinct. For example, if a friend of yours claimed that “a gene is all the DNA sequences that determine an inherited trait”, you could reply: “No, that is incorrect, because multiple genes will often determine an inherited trait.” A. “A gene is a sequence of nucleotides from...
