Question

Quizplus · Accepted Answer

Polyploidy is the condition of having multiples of the normal sets of chromosomes in a cell or organism. Therefore, an extra set of chromosomes would indicate polyploidy rather than aneuploidy (which is the condition of having an abnormal number of chromosomes within a set), diploidy (which is normal chromosome number for most somatic cells), haploidy (which is the condition of having only one set of chromosomes), or paraploidy (which is not a recognized term in cytogenetics).
