Ch 13: Meiosis and sexual life cycles Concept 13.1: Offspring acquire genes from parents by inheriting chromosome Comparison of Asexual and Sexual Reproduction In asexual reproduction, a single individual passes genes to its offspring without the fusion of gametes A clone is a group of genetically identical individuals from the same parent In sexual reproduction, two parents give rise to offspring, through the fusion of gametes, that have unique combinations of genes inherited from the two parents Concept 13.2: Fertilization and meiosis alternate in sexual life cycle Sets of Chromosomes in Human Cells Human somatic cells (any cell other than a gamete) have 23 pairs of chromosomes The two chromosomes in each pair are called homologous chromosomes, or homologs

Biology Chapter 11 Cell Division: 11.1 A) Cell Division Cell Division: the process by which a single cell becomes two daughter cells Prokaryotic cells divide by binary fission Eukaryotic cells divide by Mitosis and Cytokinesis Ori = Origin of replication (code for replication ) B) Binary Fission FtsZ, a protein it encodes forms a ring at the site of constriction where the new cell wall forms between the two daughter cells (very similar to Tublin) Cell Division in bacteria and archaeon?s occurs by binary fission Together, mitosis and cytokinesis are known as mitotic cell division. M phase (mitosis and cytokinesis) alternates with interphase, which consists of G1, S (synthesis), and G2?phases. These four stages together constitute the cell cycle.

0 10 Meiosis and Sexual Life Cycles Overview: Variations on a Theme Living organisms are distinguished by their ability to reproduce their own kind Heredity is the transmission of traits from one generation to the next Variation is demonstrated by the differences in appearance that offspring show from parents and siblings Genetics is the scientific study of heredity and variation Figure 10.1 Concept 10.1: Offspring acquire genes from parents by inheriting chromosomes In a literal sense, children do not inherit particular physical traits from their parents Inheritance of Genes Genes are the units of heredity and are made up of segments of DNA Genes are passed to the next generation via reproductive cells called gametes (sperm and eggs) Most DNA is packaged into chromosomes
