Duplication
B.
Divergence
C.
Endoreduplication
AnswerD.
Reduplication
Answer: Option C
Solution
Answer: Option C
Solution:
Polytene chromosomes are formed due to Endoreduplication.Polytene chromosomes are large chromosomes that have thousands of DNA strands. They provide a high level of function in certain tissues such as the salivary glands of insects.
Endoreduplication is the process by which a cell undergoes multiple S-phases without intervening in mitosis and its accompanying cytokinesis. This lead to the formation of Polytene chromosomes.
