Given below are two statements:
Statement I: Failure of segregation of chromatids during cell cycle resulting in the gain or loss of whole set of chromosome in an organism is known as aneuploidy.
Statement II: Failure of cytokinesis after anaphase stage of cell division results in the gain or loss of a chromosome is called polyploidy.
In the light of the above statements, choose the correct answer from the options given below:
Statement I is true but Statement II is false
Statement I is false but Statement II is true
Both Statement I and Statement II are true
Both Statement I and Statement II are false
Solution
Failure of segregation of chromatids during cell division cycle results in the gain or loss of a chromosome(s), called aneuploidy.
Failure of cytokinesis after telophase of cell division results in an increase in a whole set of chromosomes in an organism and this phenomenon is known as polyploidy.
Hence the correct answer is option (4).
