Answer:
haploid/diploid
Explanation:
The number of chromosomes can also be expressed as <em>haploid or diploid</em>, instead of 1n for one copy and 2n for two copies.
The <u>haploid number of chromosomes also refers to a copy of the chromosomes or half of the genome of organisms</u> while <u>the diploid number of chromosomes refers to the double or complete set of chromosomes in the genome of organisms. </u>
So, in other words: n = haploid and 2n - diploid.
