We examined the effects (phenotype) of the mis-expression of the Antennapedia gene (genotype) in Drosophila development. This gene is a member of an ancient gene family that humans also have and that does the same things in us. Which of the following is the most accurate and complete description of the central lesson we extracted from this examination?a. Animal genomes can have huge numbers of genes; in order to understand the control and evolution of the basic body plan it is vital to understand the details of all 10-20,000 genes in the genome and how they interact combinatorially. b.Animal genomes can have huge numbers of genes; however, only a very small number of regulators (like Antennapedia) interact combinatorially to control the body plan with remarkable informational simplicity. c.Animal genomes can have huge numbers of genes; in order to understand the control and evolution of the basic body plan it is vital to understand the details of all 10-20,000 genes in the genome and how they act independently of one another. d.Animal genomes can have huge numbers of genes; however, only a very small number of regulators (like Antennapedia) each act independently of all other regulators to control the body plan with remarkable informational simplicity.
