A scientist was collecting data about the number of chromosomes that a certain organism had. He found that most of the skin cells that he examined had a certain amount of chromosomal material, but he found some skin cells with double the chromosomal material. What might be the explanation for these findings

The cells with double amount of chromosomal materials are in G2 phase of the cell cycle.

Explanation:

The explanation for cells with double the amount of chromosomal materials of normal cells is that such cells are in G2 phase of the cell cycle.

The cell cycle consists of two main phases namely;

The interphase is sometimes referred to as the resting phase of a cell and further divided into;

The mitotic phase represents a phase of active division and is further divided into;

Hence, a cell that is observed to have double the amount of chromosomal materials of most of the other cells must have just completed the S phase of the cell cycle during which the chromosomal materials must have been double.
