2n - 1 condition is called
trisomy
monosomy

2n - 1 condition represents diploid set of chromosomes having loss of one chromosome, the presence of one unpaired chromosomes along with diploid set is called monosomy.
Trisomy is a chromosomal disorder characterized by an additional chromosome. Eg. Down syndrome.
