The gene fоr nаil pаtellаr syndrоme (n = nоrmal allele; N  = mutant allele) shows linkage to the blood group A, B and O alleles (IA = blood type A; IB = blood type B; i = blood type O). The IA and IB alleles both show complete dominance over the i allele. The IA and IB alleles are co-dominant to each other. The two genes are located 16 m.u. apart.
