Question

Which type of division leads to polyploidy?

• A. Cryptomitosis
• B. Meiosis
• C. Endomitosis
• D. Amitosis

Answer 1

The correct option is C Endomitosis

Endomitosis leads to polyploidy. Endoreplication or endomitosis is replication of the nuclear genome in the absence of cell division, which leads to elevated nuclear gene content and polyploidy. Endoreplication can be understood simply as a variant form of the mitotic cell cycle (G${}_1$-S-G${}_2$-M) in which mitosis is aborted prior to cytokinesis or circumvented entirely, due in part to modulation of cyclin-dependent kinase (CDK) activity.
