In a sample from a grasshopper population, you find four alleles at a particular locus. The frequencies of A1, A2, A3, and A4 are p1= 0.50, p2=0.30, p3=0.15, and p4=0.05. Assuming Hardy-Weinberg equilibrium, calculate the expected proportion of each of the ten possible genotypes (e.g., that of A2A3 should be […]

Project: Carrying Capacity. In 1906, the US Forest Service began protecting a herd of deer on a 300,000 hectare range on Arizona’s Kaibab Plateau. In previous years the Kaibab forest area had been overgrazed by cattle, sheep and horses. Graph the Forest Service’s data on the size of the herd […]

In cucumbers, dull fruit (D) is dominant over glossy fruit (d), orange fruit (R) is dominant over cream fruit (r), and bitter cotyledons (B) are dominant over nonbitter cotyledons (b). A plant homozygous for dull, orange fruit and bitter cotyledons is crossed with a plant that has glossy, cream fruit […]

Question: Assume you have 5mL of cells you need to treat with Hydrogen Peroxide, such that the final concentration of Hydrogen Peroxide is 5uM. How much of a 10mM stock solution of Hydrogen Peroxide would you add to your cells? Question: Locus A has two alleles (A and a) while locus B […]
