Within a large population how does conjugation benefits protists?

Conjugation begins when 2 paramecia attach to each other
Meiosis produces 4 haploid micronuclei
In each cell, 3 of the micronuclei disintegrate
The remaining micronucleus in each cell divides by mitosis
The 2 cells exchange one haploid micronucleus
In each cell the micronuclei fuse to form a single diploid micronucleus and the macronucleus disintegrates
Each cell forms a new macronucleus from its micronucleus
