Answer 1

Correct answer is (c) abnormal chromosome umber

The explanation: An erroneous meiotic division can lead to the formation of a gamete that contains abnormal number of chromosomes. When such gametes fuse with a normal gamete, the resulting zygote contains an abnormal chromosome number, this condition is termed aneuploidy.
