The daughter cells from mitosis are called diploid cells. Diploid cells have two complete sets of chromosomes. Since the daughter cells have exact copies of their parent cell's DNA, no genetic diversity is created through mitosis in normal healthy cells.

(Science: molecular biology) The full use of the information in a gene via transcription and translation leading to production of a protein and hence the appearance of the phenotype determined by that gene.xpressed gene.

Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein.1  When the information stored in our DNA is converted into instructions for making proteins or other molecules, it is called gene expression. Gene expression is a tightly regulated process that allows a cell to respond to its changing environment. 2  It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.
