How does codominance at the molecular level help to explain why evolutionary processes haven't resulted in the elimination of the sickle-cell allele among people of African descent? Individuals with two sickle-cell alleles are immune to infection by the malaria parasite. Heterozygous individuals have only normal hemoglobin and have immunity to infection by the malaria parasite. None of the listed responses is correct. Only individuals homozygous for the normal hemoglobin allele survive to adulthood. Heterozygous individuals have both normal and sickle- cell hemoglobin in their red blood cells and reduced vulnerability to malaria.

2.19 For a K$^+$ - Cl$^-$ ion pair, attractive and repulsive energies $E_A$ and $E_R$, respectively, depend on the distance between the ions $r$, according to: $E_A = -(1.436/r)$ $E_R = (5.86 \times 10^{-6})/r^9$ For these expressions, energies are expressed in electron volts per K$^+$ - Cl$^-$ pair, and $r$ is the distance in nanometers. The net energy $E_N$ is just the sum of the preceding two expressions. (a) Superimpose on a single plot $E_N$, $E_R$, and $E_A$ versus $r$ up to 1.0 nm. (b) On the basis of this plot, determine (i) the equilibrium spacing $r_0$ between the K$^+$ and Cl$^-$ ions, and (ii) the magnitude of the bonding energy $E_0$ between the two ions. (c) Mathematically determine the $r_0$ and $E_0$ values using the solutions to Problem 2.18 and compare these with the graphical results from part (b).
