Question

which process occurs after nuclear changes in paramecium??​

Answer 1

Answer:

In Paramecium, Conjugation is a form of sexual reproduction. It is a temporary union of two individuals of same species for mutual exchange of genetic materials. Continuous multiplication by binary fission is interrupted by conjugation as it is necessary for the survival and rejuvenation of the race

In a study of the nuclear behavior of Paramecium aurelia, a process of self‐fertilization, autogamy, has been discovered and traced through its essential steps. Autogamy is the counterpart, in a single animal, of conjugation. In autogamy, three micronuclear divisions lead to the formation of the gametic nuclei. These divisions are considered to be maturation divisions. The first division is characterized by a great increase in the size of the two vegetative micronuclei and the occurrence of long thread‐like crescents. The second division results in the formation of eight nuclei, variable numbers of which continue to divide giving rise to the potential gametic nuclei. Two of the latter unite to form a synkaryon. The old macronucleus disintegrates. The fusion nucleus divides twice: two of the daughter nuclei become macronuclear anlagen, while the other two remain micronuclei. The macronuclear anlagen are distributed to two daughter cells at the time of the first cell division, when the micronuclei divide.
