็Heritabilit estimates for CBC traits in our study were shown to be moderate for WBC traits, including total WBC, neutrophils, lymphocytes, and monocytes, and high for eosinophils. For the RBC and Hb were highly heritable whereas MVC, MCH and RAW were moderately heritable but platelet count was lowly heritable. With most traits being moderately to highly heritable, a fairly large genetic component for CBC traits is indicated.
