____Is Viewed as a Major Cause of Aneuploidy

Question

____is viewed as a major cause of aneuploidy.
A)X- ray mutations
B)Heat treatment
C)Segmental deletions
D)Colchicine treatment
E)Nondisjunction

Accepted Answer

Nondisjunction is the failure of chromosome segregation during cell division, leading to an abnormal number of chromosomes in daughter cells. This can result in aneuploidy (having more or fewer than the normal number of chromosomes) which can cause genetic disorders such as Down syndrome. The other options listed are mutagens or physical treatments that can lead to genetic changes, but they are not specifically linked to aneuploidy.
