Results: The percentage of blood group A is highest in cleft lip and palate patients , and blood group B was lowest, Rh+ were found to be 91.02% and there was a significant difference between cleft group and Iraqi national bank , with no significant difference between different cleft types.

Conclusions: Although blood types are genetically inherited the environment potentially can determine which types in population will be passed on more frequently to the next generation.
