What is the difference between a gene tree and anorganismal tree?

Segregation and independent assortment are LEAST likely to be exhibited by genes in a) Escherichia coli b) Arabidopsis thaliana c) Caenorhabditis elegans d) Drosophila melanogaster e) Neurospora crassa

Based on our modern understanding, what revisions are necessary to the original one-gene / one-enzyme hypothesis? (Check all that apply.) Alternative splicing allows one gene to encode multiple polypeptides. Some genes encode RNAs, not enzymes. Some genes encode lipids, not enzymes. Some genes encode polypeptides that are not enzymes, such as structural proteins. Proteins as functional units may be composed of several polypeptides, so genes may encode just one polypeptide within a larger protein. Enzymes are not encoded by genes after all — they are constructed through separate biochemical processes.
