A student uses gummy worms to model the process of mitosis. The model is shown below.

Question

Using the model, which statement correctly explains how mitosis preserves genetic continuity?
a
The daughter cells receive chromosomes that are identical to the parent cell.
b
Each daughter cell receives twice as many chromosomes as the parent cell.
c
Each daughter cell receives half of its chromosomes from each of the parent cells.
d
The daughter cells receive chromosomes that are recombined from the parent cells.

Answer 1

The correct statement that explains how mitosis preserves genetic continuity is:

a. The daughter cells receive chromosomes that are identical to the parent cell.

During mitosis, a single parent cell divides to produce two daughter cells that are genetically identical to the parent cell, maintaining the same chromosome number and genetic information.
