Chapter 15 The Chromosomal Basis of Inheritance Overview: Locating Genes Along Chromosomes Mendel?s ?hereditary factors? were genes, though this wasn?t known at the time Today we can show that genes are located on chromosomes The location of a particular gene can be seen by tagging isolated chromosomes with a fluorescent dye that highlights the gene Copyright ? 2008 Pearson Education Inc., publishing as Pearson Benjamin Cummings Fig. 15-1 Concept 15.1: Mendelian inheritance has its physical basis in the behavior of chromosomes Mitosis and meiosis were first described in the late 1800s The chromosome theory of inheritance states: Mendelian genes have specific loci (positions) on chromosomes Chromosomes undergo segregation and independent assortment
