Understanding Haploid Nucleus Division in Mitosis

Explanation:

When a haploid nucleus undergoes three rounds of mitosis, the following process occurs:

Step 1: One haploid nucleus divides by mitosis, resulting in two nuclei.

Step 2: Each of the two nuclei then undergoes mitosis and divides, producing a total of four nuclei.

Step 3: Finally, each of the four nuclei from the second round of division undergoes mitosis again, resulting in a total of eight haploid nuclei.

This process illustrates how a single haploid nucleus can multiply through mitosis to produce eight haploid nuclei, demonstrating the outcome of division by mitosis repeated three times.
