_ 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
