The model shows the process of binary fission.
slava [35]

Answer:

<em>The correct option is B) Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.</em>

Explanation:

Genetic continuity can be described as a fact that the daughter cells have the same amount and same type of genome as the parent cell. It includes the transfer of parental traits to children.

Binary fission can be described as a process of division which bacteria divides. Two daughter cells are produced as a result of binary fission. Each daughter cell is identical to the parent cell and hence maintains genetic continuity.
