Inherited a resistance to malaria
Explanation:
Errol's father carries two recessive genes for sickle-cell anemia, and Errol's mother carries two normal dominant genes. Therefore, Errol has inherited a resistance to malaria from his parents.
Errol will have a heterozygous genotype (AS). Scientifically, individuals that a carriers of the sickle cell allele have been reported to be resistant to malaria causing protozoa called plasmodium unlike the homozygous dominant allele AA which is susceptible to malaria infection or the recessive allele SS which causes sickle cell disease.
