Not yet answered Points out of 2.00 Flag question Of the following, what is the probable explanation that patients infected with HIV having heterozygous HLA loci progress to AIDS more slowly than those patients who have one or more homozygous HLA loci? Select one: O a. The greater number of HLA alleles provides a wider variety of HLA molecules for presenting HIV-derived peptides to CD8 T cells even if HIV mutates during the course of infection. O b. Heterozygotes have more opportunity for interallelic conversion and can therefore express larger numbers of MHC alleles. O c. Od. Directional selection mechanisms favor heterozygotes and provide selective advantage to pathogen exposure. As heterozygosity increases, so does the concentration of alloantibodies in the serum, some of which cross- react with and neutralize HIV.
