Quizplus · Accepted Answer

A chromosome number of 2n+1 indicates that there is an extra chromosome present. This is commonly seen in trisomy conditions, such as Down syndrome, where an individual has three copies of chromosome 21 instead of the normal two copies. A person with monosomy would have a chromosome number of 2n-1, indicating that they are missing a chromosome. This is typically seen in conditions such as Turner syndrome, where females only have one X chromosome instead of the normal two.
