DNA fingerprinting relies on the variation in which type of DNA sequences? MCQ with Answer and Explanation

Explanation:
Lymphatic filariasis, commonly known as elephantiasis, is a parasitic disease caused by nematode worms, primarily Wuchereria bancrofti. The infective larvae (microfilariae) are transmitted to humans through the bite of an infected female Culex mosquito (primarily Culex pipiens fatigans). The adult worms lodge in the lymphatic vessels, causing severe inflammation, blockage, and the characteristic massive swelling (elephantiasis) of the limbs and genitals. Anopheles transmits malaria, Aedes transmits dengue.

Explanation:
Frogs belong to the class Amphibia, characterized by a life cycle that includes an aquatic larval stage (tadpole) with gills and an adult stage with lungs, moist skin, and a three-chambered heart. Turtle, snake, and lizard are reptiles, with dry scaly skin and amniotic eggs. Amphibians are the first terrestrial vertebrates but depend on water for reproduction.
