_ reproduction is a means of creating new individuals solely by _, the form of cell division that creates genetically identical daughter cells.
asexual, mitosis
A _ is a lump of abnormal cells that, although growing out of control, remains at its original sight
benign tumor
The cells produce this way will be _, Meaning that they contain a single set of chromosomes. Such cells are produced only in the _.
haploid, gonads
A _ is an abnormally growing mass of cells that is actively spreading through the body.
malignant tumor
_ reproduction, in contrast, generates genetically unique offspring. To accomplish this, an organism must produce _, sperm and egg, through the process of _.
sexual, gametes, meiosis
