Question

Polyploidy means having
A) only one set of chromosomes.
B) an abnormal number of two or more individual chromosomes.
C) three or more sets of chromosomes.
D) an abnormal number of one particular chromosome.
E) three or more chromosomes.

Accepted Answer

Polyploidy refers to having more than two sets of chromosomes, which can result from the fusion of two or more gametes or errors during cell division. Having only one set of chromosomes is monoploidy, an abnormal number of two or more individual chromosomes is aneuploidy, an abnormal number of one particular chromosome is monosomy or trisomy, and having three or more chromosomes is not specific enough to categorize.
