Why do we give emphasis in selection for the genotype?

Emphasizing selection for genotype is important because the genotype represents an organism's genetic makeup, which determines its physical traits, behavior, and overall fitness. By selecting for specific genotypes, we can influence the genetic diversity, health, and productivity of a population. This can be important in breeding programs for agriculture, livestock, and wildlife conservation, as well as in medical research for identifying genetic factors related to disease susceptibility and treatment effectiveness. Ultimately, selecting for specific genotypes can help improve the overall quality and performance of a population.
