During conjugation in Paramecium:

Question

During conjugation in Paramecium: (A) the zygote nucleus undergoes eight successive divisions in each conjugant (B) out of the twelve macronuclei formed, four nuclei degenerate (C) out of the four micronuclei formed, three nuclei degenerate (D) out of the sixteen nuclei formed from the zygote nucleus, twelve become macronuclei and four become micronuclei

Tardigrade Admin · Accepted Answer

In conjugation, the nucleus of the synkaryon divides 3 times to form 8 nuclei. Out of these, 4 become macronuclei and remaining 4 are micronuclei. Out of these 4 micronuclei, 3 degenerate and only single micronucleus remains present.
