You will recall that the HWE equation is p + q = 1 (or p 2 + 2 pq + q 2 = 1 ). Use that to answer the following: 2. When a physician/med. tech./nurse evaluates your blood type, they often include a tor after the letter (for example, Dr. Nielsen's blood type is A+). This characteristic of red blood cells is called the Rhesus factor and the allele that codes for the factor is dominant over a mutated form of the gene that results in the factor being absent from red blood cells. A population of 900 students was surveyed to determine the frequency of positive and negative blood types. Ninety-three percent of the students are R h -positive, that is, they have the Rhesus factor. If the population is in HWE, how many students would have each of the following genotypes: homozygous dominant, heterozygous, and homozygous recessive?.
