At least three hemoglobin alleles in human populations alterhemoglobin structure in such a way as to impair the transportof O2 by the blood but enhance resistance of red blood cells toparasitization by malaria parasites. Explain how such allelesexemplify pleiotropy, and discuss whether such alleles couldlead to nonadaptive evolution of blood O2 transport in certainsituations.

In most species of mammals, the O2 affinity of a fetus’s bloodhemoglobin is greater than that of its mother’s blood hemoglobin.However, mammal species are not all the same in the mechanismthat causes the affinities to be different. Specify three distinctmechanisms for the difference in affinity between fetal andmaternal blood hemoglobin. Considering the mechanism of the fetal–maternal difference in O2 affinity, would you say that the evolution of themechanism provides evidence for Jacob’s argument? Explain.
An allele of the G6PD gene acts in a recessive manner to cause sensitivity to fava beans, resulting in ahemolytic reaction (lysis of red blood cells) afteringestion of the beans. The same allele also confersdominant resistance to malaria. The heterozygote hasan advantage in a region where malaria is prevalent.Will the equilibrium frequency (qe) be the same foran African and a North American country? Whatfactors affect qe?
Heterozygotes at the sickle-cell locus produce both normal and abnormal sickle-cell hemoglobin. When hemoglobin molecules are packed into a heterozygote’s red blood cells, some cells receive relatively large quantities of abnormal hemoglobin, making these cells prone to sickling. Explain how these molecular and cellular events lead to emergent properties at the individual and population levels of biological organization.
Which of the following proteins is thought to have been the first to evolve from an ancestral gene duplication of the most ancient O2 transporting protein in vertebrate hemoglobin (found today in all vertebrates except the agnathan fishes)? A. gamma-globin (-globin) B. epsilon-globin (-globin) C. alpha-globin (-globin) D. delta-globin (-globin) E. zeta-globin (-globin)
The larvae of the fruit fly Drosophila melanogaster normally feedon rotting fruit, which may ferment and produce high concentrations ofalcohol. Douglas Cavener and Michael Clegg studied allelic frequenciesat the locus encoding alcohol dehydrogenase (Adh) in experimentalpopulations of D. melanogaster (D. R. Cavener and M. T. Clegg. 1981.Evolution 35:1–10). The experimental populations were establishedfrom wild-caught flies and were raised in cages in the laboratory. Twocontrol populations (C1 and C2) were raised on a standard cornmeal–molasses–agar diet. Two ethanol populations (E1 and E2) were raised ona cornmeal–molasses–agar diet to which was added 10% ethanol. Thefour populations were periodically sampled to determine the frequenciesof two alleles at the alcohol dehydrogenase locus, AdhS and AdhF. Thefrequencies of these alleles in the four populations are shown in theaccompanying graph. a. On the basis of these data, what conclusion might you draw about theevolutionary forces…

In a natural population of Drosophila melanogaster, thealcohol dehydrogenase gene has two alleles calledF (fast) and S (slow) with frequencies of Adh-F at 0.75and Adh-S at 0.25.
