Biologists refer to the number of chromosomes with an "#n". For example, 1n for one copy of chromosomes and 2n for two copies. How else can this be expressed?

haploid/diploid

Explanation:

The number of chromosomes can also be expressed as haploid or diploid, instead of 1n for one copy and 2n for two copies.

The haploid number of chromosomes also refers to a copy of the chromosomes or half of the genome of organisms while the diploid number of chromosomes refers to the double or complete set of chromosomes in the genome of organisms.

So, in other words: n = haploid and 2n - diploid.

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
