When 1,000 donors were tested, 75% were positive for C and 25% were negative for C; the gene frequency of C is:

Question

Quizplus · Accepted Answer

Gene frequency is the proportion of a particular allele in a population. In this case, if 75% of the donors tested positive for C, then the gene frequency of C is 0.75 or 75%. This means that C is present in the population at a frequency of 0.75 or 75%, which is the same as saying that 75 out of every 100 alleles is C. Therefore, the best choice is (C) 0.5.
