Chromosome abnormalities usually happen as a result of an error in cell division. Meiosis is the name used to describe the cell division that the egg and sperm undergo when they are developing. Normally, meiosis causes a halving of chromosome material, so that each parent gives 23 chromosomes to a pregnancy.
All new cells come from previously existing cells. New cells are formed by karyokinesis-the process in cell division which involves replication of the cell s nucleus and cytokinesis-the process in cell division which involves division of the cytoplasm.Two types of nuclear division include mitosis and meiosis.eiosis results in the formation of either gametes in animals or spores in plants. The cells formed have half the chromosome number of the parent cell. Mitosis is best observed in cells that are growing at a rapid pace, such as in the whitefish blastula or onion root cell tips.
