Answer 1

In asexual reproduction, such as binary fission in bacteria, the offspring are genetically identical to the parent cell. When considering the third generation of a bacterium and the original parent cell, the DNA sequence of the offspring will be 100% identical to that of the parent cell, as no genetic variation is introduced without external forces (e.g., mutation, genetic recombination, or horizontal gene transfer).

Therefore, the correct answer is:

100%
