    BACKGROUND: Mycobacterium tuberculosis causes tuberculosis, one of the world’s deadliest diseases. It is an acid-fast bacillus that is 2-4 um in length and 0.2-0.5 um in width. How many weeks, days,& hours would it take to see a M.tuberculosis colony on solid media? Its generation time is listed in the reading (above). Assume that bacterial colonies are not visible to the naked eye unless they contain ≥ 2 millioncells. This species forms aggregates of 5 cells on average. Show your...

    2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
