ECOLOGICAL SIGNIFICANCE OF HAEMOGLOBIN VARIATION IN TWO SPECIES OF FROGS | BIONATURE

In the presence of B-mercaptoethanol, the haemoglobin of two species of frogs, as well as normal human haemoglobin, was damaged. In both species of frog, globin chain analysis reveals two different bands that are partially similar to human and globin chains, respectively. The only difference is that the electrophoretic mobility of these two globin bands is slower than that of human globin bands. When compared to frogs of the same species living in warmer places over the same time period, frogs living in cooler regions near deserts have a slower moving haemoglobin band.
