Happens in almost all cells (Somatic cells). 1 parent cell. Chapter 8. Asexual vs. Sexual reproduction. Asexual reproduction – new organisms/cells are genetically identical to parent cells/organisms . Sexual reproduction – offspring have a combination of genes from both parents. . ch. : 7. Sexual or Asexual. Asexual – involves a single parent organism and produces off-spring or daughter cells that are clones. Sexual Reproduction – involves genetic contribution in the form of gametes from two sources. Chapter . 11. Genes and Development. Fig. 11.1. Copyright © The McGraw-Hill Companies, Inc.
