(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Kalinga Frog
- The Kalinga Frog (Fejervarya Kalinga) was recently identified species which was documented in 2018.
- The species was encountered several times during field expeditions in the Western Ghats. However, the physical characteristics vary entirely from the known species of Eastern Ghats.
- However, it has been reported from the central Western Ghats, with the evidence of considerable MPP.
- It was the only genetic analysis that helped prove that physically different-looking frogs from eastern and western ghats were the same.
What is MPP?
- The morphological phenotypic plasticity (MPP) is the ability of an organism to show drastic morphological (physical features) variations in response to natural environmental variations or stimuli.
- The term “phenotype” refers to the observable physical properties of an organism, which include the organism’s appearance, development, and behaviour.
