Division of the exconjugant into daughter paramoecia, Biology

Division of the exconjugant into daughter paramoecia:
  • Each exconjugant, with a single micronucleus and four macronuclei divides twice and forms four daughter paramoecia.
  • Each daughter paramoecium receives one macronucleus from the exconjugant.
  • The single micronucleus of the exconjugant divides twice along with the exconjugant and each daughter paramoecium receives one micronucleus.
  • Thus each of the four daughter paramoecia receive one macro and one micro nuclei
  • Note that only the micronucleus of the exconjugants undergoes mitotic division while the macronuclei does not divide. They are distributed to the daughter
  • paramoecia from the exconjugant.
  • Thus by conjugation a single paramoecium produces four daughter paramoecia.
  • Finally at the end of conjugation 8-daughter paramoecia are formed from two parental paramoecia.
