Chapter 8 - The cellular basis of reproduction and inheritance. The main contents of this chapter include all of the following: Cell division and reproduction, the eukaryotic cell cycle and mitosis, meiosis and crossing over, alterations of chromosome number and structure. | Chapter 8 The Cellular Basis of Reproduction and Inheritance 0 Cancer cells start out as normal body cells, undergo genetic mutations, lose the ability to control the tempo of their own division, and run amok, causing disease. 0 Introduction © 2012 Pearson Education, Inc. In a healthy body, cell division allows for growth, the replacement of damaged cells, and development from an embryo into an adult. In sexually reproducing organisms, eggs and sperm result from mitosis and meiosis. 0 Introduction © 2012 Pearson Education, Inc.

Cell division plays many important roles in the lives of organisms Organisms reproduce their own kind, a key characteristic of life. Cell division is reproduction at the cellular level, requires the duplication of chromosomes, and sorts new sets of chromosomes into the resulting pair of daughter cells. 0 © 2012 Pearson Education, Inc. Cell division is used for reproduction of single-celled organisms, growth of multicellular organisms from a fertilized egg into an adult, repair and replacement of cells, and sperm and egg production. 0 Cell division plays many important roles in the lives of organisms © 2012 Pearson Education, Inc. Cell division plays many important roles in the lives of organisms Living organisms reproduce by two methods. Asexual reproduction produces offspring that are identical to the original cell or organism and involves inheritance of all genes from one parent. Sexual reproduction produces offspring that are similar to the parents, but show variations in traits and involves inheritance of unique sets of genes from two parents. 0 © 2012 Pearson Education, Inc.
