1. a. A standard solution of a protein containing 0.400 mg/ml had an absorbance of 0.312 at 280 nm. The pathlength of the cuvette is 1 cm (b= 1 cm). Calculate the extinction coefficient (mg-1 * cm-1 * mL) of the standard protein and write your final answer in the […]

Once two populations of a species have become allopatric with some barrier preventing gene flow between them, the two populations are free to diverge genetically. One mechanism for divergence that is thought to result in rapid divergence is sexual selection. a. Why is sexual selection likely to result in more […]

Q1. In a population that has been mating randomly for many generations, two phenotypes are segregating; one is by reason of the dominant allele D, and the other to a recessive allele d. The frequencies of the dominant and recessive phenotypes are 0.7975 and 0.2025, respectively. Find out both the […]
