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.

Mike was adopted, and his biological family history is unknown. although he is healthy, he would like some understanding of his genetic makeup, including potential health risks and genes that he could pass on to his children. mike has heard about commercial laboratories that can compare segments of your dna to those of people with common hereditary diseases in order to give you some idea of how susceptible you are to the diseases. the results of these types of tests are highly inconclusive. if mike's dna showed that he shares similarities in a segment of dna with people who have a given disease, his chances of developing that disease or passing it on to his children may be slightly elevated, but they are not 100 percent. these tests can cost more than $2,500 and are not covered by many insurance companies. do you think that mike should undergo the genetic tests? explain your answer. what are the potential pros and cons of having such tests done? describe how the availability of these genetic tests might affect the frequency of genetic diseases in individuals and populations.

In a lab, scientists grew several generations of offspring of a plant using the method shown. what conclusion can you make about the offspring? a. they formed from meiosis and mitosis. b. they have half the number of chromosomes as their parent. c. they have low genetic variability among them. d. they will be able to reproduce only after they grow flowers.

What is one reason why transpiration is important in plants? question 19 options: it produces food from the sugar in the plant cells. it enables the flow of water out of the plant. it produces carbon dioxide in the leaves of the plant.
