In the experiment, we will establish microcosms to test the effect of illumination on relative abundance of our two ciliate phenotypes. You will use 3 beakers filled with water, and will inoculate these beakers with a mixed culture containing both phenotypes. Inoculation will involve adding a small volume of the […]

Suppose that the average per amino acid site substitution rate in mammalian fibrinogen b (roughly 600 amino acids long) is one substitution every 10 million years. If humans and shrews […]

Question: A soybean mutant exhibiting a tan colored seed coat was recently identified. Crossing the mutant with the the wild-type,yellow-seeded soybean plant gave all yellow -seeded soybeans in the first generation, F1. Self-pollination of F1 provided in the second generation ,F2,814 yellow seeded and 201 tan-seeded plants.This pattern suggests a simple […]
