Vedclass · Answer

(A) Aneuploidy is a condition characterized by the gain or loss of one or more chromosomes,resulting in an abnormal chromosome number that is not an exact multiple of the haploid set. This occurs due to the failure of segregation of chromatids during cell division (nondisjunction). In contrast,polyploidy refers to the addition of an entire set of chromosomes (e.g.,$3n, 4n$). Therefore,the correct definition of aneuploidy is the addition or deletion of one or more chromosomes to the total number.
