Genome size (the length of DNA associated with one haploid complement of chromosomes) varies substantially between different organisms. Because more genes are required to direct the formation of more complex organisms, it is not surprising that genome size is roughly correlated with an organism’s apparent complexity. Which of the following statements is/are correct in reference to this rough correlation?

I. Many organisms of apparently similar complexities have very different genome sizes.

II. The number of genes, rather than genome size, is more closely related to organism complexity.

III. There is a roughly inverse correlation between organism complexity and gene density—the less complex the organism, the higher the gene density.

IV. Gene density in eukaryotic organisms is consistently higher and more variable than in their prokaryotic counterparts.

Assume that mating is random. First, consider an autosomal recessive disease that is usually lethal in childhood, and that has an incidence among newborns of 1/3000. What mutation rate would be required to maintain this frequency in the population?
