What genotype is found most frequently in the Caucasian population?

The genotype found most frequently in the Caucasian population is CDe/ce. This refers to the Rh blood group system, where 'C' and 'c' represent different alleles at one locus, and 'D' represents the presence or absence of the Rh factor, which is important in transfusion medicine and pregnancy compatibility.

In the context of population genetics, the frequency of specific genotypes can vary significantly among ethnic groups due to historical migration patterns, genetic drift, and selection pressures. The CDe and ce alleles are specifically relevant in Caucasian populations, demonstrating higher frequencies compared to other ethnicities.

The other genotypes listed may be relevant in broader genetic discussions but do not specifically highlight the commonality within the Caucasian population. For instance, AaBb and Hh represent general heterozygosity at different loci and are not specific enough to indicate a common genotype in a particular ethnic group. The ABO/O choice pertains to blood types rather than a precise genotype associated with ethnicity and does not reflect the high prevalence of the CDe/ce genotype in Caucasians. Thus, CDe/ce is the most accurate representation of the most frequent genotype in this demographic context.
