Question

In mammals, the majority of cardiomyocytes (cardiac muscle cells) undergo repeated DNA replication without cytokinesis as a part of normal development, and in response to injury or heart attack. Many cardiomyocytes are tetraploid, and some cells have even higher DNA content. This variation in DNA content is an example of

A. alloploidy.
B. aneuploidy.
C. endopolyploidy.
D. copy number variation.

Answer 1

C. endopolyploidy

Step-by-step explanation:

Endopolyploidy occurs in cardiomyocytes cycles that are often known to have variants of DNA content.
