Formation of pronuclei , Biology

Formation of pronuclei :
  • Information of pronuclei, micronucles which is one of the conjugants, plays an important role.
  • Micronucleus undergoes meiosis and forms four haploid daughter nuclei. 
  • Of these 4 daughter nuclei three disappear.
  • The remaining micronucleus divides into a small and a large nucleus.
  • The smaller nucleus is called male pronucleus or migratory pronucleus.
  • The large one is called female pronucleus or stationary pronucleus.
  • In this way, pronuclei are formed in paramoecium during conjugation.
