Solution
The correct option is A Trisomy
When the chromosome number of a given organism has one additional chromosome in one of the homologous pairs, the condition is known as trisomy. This condition can be represented as - (2n+1).
Monosomy is a form of aneuploidy with the presence of only one chromosome from a pair.And this condition can be represented as - 2n-1.
Polyploid cells/organisms are those containing more than two paired (homologous) sets of chromosomes.
Nullisomy is a genetic condition involving the lack of both the normal chromosomal pairs for a species (2n-2).
