What is the gene frequency of Jk^a in the provided population?

To determine the gene frequency of Jk^a within a population, one must understand the underlying genetics, particularly how allele frequencies relate to phenotypic expression in the context of blood group antigens. The gene frequency represents the proportion of alleles in a population that corresponds to a specific gene variant, in this case, the Jk^a allele.

In this scenario, the selection of Jk^a has been calculated as 0.55, indicating that in this population, approximately 55% of the alleles at the relevant locus are for Jk^a. Gene frequencies are typically derived from genetic studies or blood type frequency distributions within a specific population group and reflect the proportion of individuals expressing the Jk^a phenotype as a result of these alleles.

A frequency of 0.31, 0.45, or 0.60 would either underestimate or overestimate the prevalence of Jk^a in this specific context, suggesting discrepancies with documented genetic research on this blood group system. Understanding that Jk^a is highly prevalent in certain populations contributes to supporting the chosen frequency and helps clinicians and researchers anticipate compatibility issues in blood transfusions or organ transplants. Thus, the reported gene frequency of 0.55
