As discussed previously, the ABO locus in humans has three alleles, where IAand IBare co-dominant and i is recessive to each. Suppose that, in a large population at equilibrium, the frequency of the IA allele is 0.35 and the frequency of the IB allele is 0.15.

a. What is the expected frequency of people with type AB blood in this population?
b. What is the expected frequency of people with type A blood?
c. A blood bank collects 5000 pints of blood during a blood drive and finds that 1850 were type A, 635 were type B, 180 were type AB and 2335 were type O. Calculate the frequencies of the IA ,IB, and i alleles in this population. (Hint: you should first determine the iallele frequency.

The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )
