Why parental genotypes higher than recombinant ones?

Parental genotypes are often more frequent than recombinant ones due to the phenomenon of genetic linkage, where genes located close together on the same chromosome tend to be inherited together during meiOSis. This results in less recombination between these linked genes, leading to a higher proportion of offspring exhibiting parental combinations of alleles. Additionally, if the parental genotypes are favored by selection, they may persist at higher frequencies in the population compared to recombinants.
