In sickle cell trait, number of bands found in Hb

Ans. is 'a' i.e., 2 In hemoglobin electrophoresis, various types of hemoglobin move at varying speed. In sickle cell trait (heterozygous state), there are two types of hemoglobin - HbS (40%) and HbA (60%). So, on electrophoresis two different bands are produced. In Homozygous state, almost all hemoglobin is HbS. So, single band is produced. Laboratory findings of sickle cell anemia Moderate to severe anaemia o Peripheral smear will show Sickle cells Howell - Jolly bodies because of autosplenectomy Target cells o A positive sickling test with a reducing substance like sodium metabisulfite.
