ECOLOGICAL SIGNIFICANCE OF HAEMOGLOBIN VARIATION IN TWO SPECIES OF FROGS

The haemoglobin of two species of frog along with the normal human haemoglobin was broken in the presence of B-mercaptoethanol. The globin chain analysis shows two distinct bands in both the species of frog which partly resemble to that of human α and β globin chains respectively. Only difference is that these two globin bands have relatively slow electrophoretic mobility than human globin bands. The frogs inhabiting in colder region near desert exhibit slow moving haemoglobin band when compared to frogs of the same species inhabiting warmer areas in the same period.
