Use the following information to answer the questions below.
In a hypothetical population of 1,000 people, tests of blood-type genes show that 160 have the genotype AA, 480 have the genotype AB, and 360 have the genotype BB.
-If there are 4,000 children born to this generation, how many would be expected to have AB blood under the conditions of Hardy-Weinberg equilibrium?

Question

Quizplus · Accepted Answer

Under Hardy-Weinberg equilibrium, the frequency of the AB genotype is calculated as 2pq, where p and q are the frequencies of the A and B alleles, respectively. Here, p = (2*160 + 480)/2000 = 0.4 and q = (2*360 + 480)/2000 = 0.6. Thus, 2pq = 2*0.4*0.6 = 0.48. Therefore, the expected number of AB children is 0.48 * 4000 = 1,920.
