In a way, yes.
Most one celled critters don't have paired chromosomes the way the plants and animals that we are familiar with do. They are called "haploid" while the others are called "diploid"
The exchange or insertion of genetic information among haploid critters has far more impact than among diploids.
The redundancy of extra sets has a stablizing effect.
Just to make matters more confusing, especially among plants, there can be sets of four or more of each chromosome.
Do you have a link to the haploid/diploid information on single celled organisms?
If my memory is correct, haploid is meiosis (reproductive cells in sexually reproducing organisms) and diploid are somatic cells.
