Final answer:
In paramecia, genes are exchanged during conjugation, the parental paramecia contribute genes to the offspring, and paramecia exchange micronuclei. Conjugation is not exactly like sexual reproduction in higher animals and paramecia are not exclusively haploid.
Step-by-step explanation:
The statements concerning conjugation in paramecia that are true are: Genes are exchanged during conjugation, The parental paramecia contribute genes to the offspring of the coupling, and Paramecia exchange micronuclei.
Conjugation in paramecia is a form of sexual reproduction but it is not exactly like the sexual reproduction observed in higher animals. Rather than combining half the genetic material from two parents to produce offspring, conjugation involves two paramecia coming together and exchanging micronuclei, which contain genetic material. This process contributes to genetic diversity, but it doesn't result in the production of offspring. After the exchange, each paramecium goes away to reproduce asexually, passing the new genetic material onto its offspring.
Lastly, it's not correct to state that paramecia are exclusively haploid. Paramecia have a complex nuclear apparatus, consisting of a large, polyploid macronucleus and one or two small micronuclei that are diploid.
