An example to prove the point is sickle cell anemia. The genotype of sickle cell is caused by a single base pair change in the beta-globin gene: normal=GAG (glu), sickle=GTG (val). There are several phenotypes associated with the sickle genotype: -. 1  anemia (a recessive trait).2  blood cell sickling (co-dominant).3  altered beta-globin electrophoretic mobility (co-dominant).n example to prove the point is sickle cell anemia.
