In general, in the developmental history of a mammalian heart, it is observed that it passes through a two-chambered fish-like heart, three-chambered frog-like heart and finally to four-chambered stage. To which hypothesis can this above cited statement be approximated?
-
- Hardy-Weinberg Law
- Lamarck's Principle
- Biogenetic Law
- Mendelian Principles
Correct Option: C
Hardy - Weinberg law is the principle of genetic equilibrium according to which in the absence of external environmental disturbances, a randomly mating population remains in genetic equilibrium. Lamarck postulated the theory of inheritance of acquired characters. Mendelian principles explained the inheritance of genetic characters from one generation to another.
