Question

Meiosis leads to all of the following except

• A. Gametogenesis
• B. Oogenesis
• C. Pangenesis
• D. Spermatogenesis

Answer 1

The correct option is C Pangenesis

• Pangenesis was Charles Darwin's hypothetical mechanism for heredity, in which he proposed that each part of the body continually emitted its own type of small organic particles called gemmules that aggregated in the gonads, contributing heritable information to the gametes.
  
• Pangenesis mirrored ideas originally formulated by Hippocrates and other pre-Darwinian scientists, but built off of new concepts such as cell theory, explaining cell development as beginning with gemmules which were specified to be necessary for the occurrence of new growths in an organism, both in initial development and regeneration.
  
• It also accounted for regeneration and the Lamarckian concept of the inheritance of acquired characteristics, as a body part altered by the environment would produce altered gemmules.
  
• This made Pangenesis popular among the neo-Lamarckian school of evolutionary thought.
  

So the correct option is 'pangenesis'.
