Chapter 15 The Chromosomal Basis of Inheritance Lecture Outline Overview: Locating Genes on Chromosomes Genes are located on chromosomes. Concept 15.1 Mendelian inheritance has its physical basis in the behavior of chromosomes Around 1900, cytologists and geneticists began to see parallels between the behavior of chromosomes and the behavior of Mendel?s factors. Using improved microscopy techniques, cytologists worked out the process of mitosis in 1875 and meiosis in the 1890s. Chromosomes and genes are both present in pairs in diploid cells. Homologous chromosomes separate and alleles segregate during meiosis. Fertilization restores the paired condition for both chromosomes and genes.

Chapter 14 Mendel and the Gene Idea Lecture Outline Overview: Drawing from the Deck of Genes The ?blending? hypothesis popular 1800s This hypothesis proposes that genetic material contributed by each parent mixes in a manner analogous to the way blue and yellow paints blend to make green. With blending inheritance, a freely mating population will eventually give rise to a uniform population of individuals. Everyday observations and the results of breeding experiments tell us that heritable traits do not blend to become uniform. An alternative model: the ?particulate? inheritance proposes that parents pass on discrete heritable units, genes, that retain their separate identities in offspring. Genes can be sorted and passed on, generation after generation, in undiluted form.

Copyright ? 2011 Pearson Education, Inc. -1- Name_______________________ Period___________ Chapter 15: The Chromosomal Basis of Inheritance Concept 15.1 Mendelian inheritance has its physical basis in the behavior of chromosomes 1. What is the chromosome theory of inheritance? The chromosome theory of inheritance is a basic principle in biology stating that genes are located at specific positions (loci) on chromosomes and that the behavior of chromosomes during meiosis accounts for inheritance patterns. 2. Explain the law of segregation. Use two different colored pencils to illustrate the segregation of alleles. You may want to consult Figure 15.2 in your text, and model your sketches on this.

Key Concepts ? Inherited traits are affected by genes. ? Genes are composed of the chemical deoxyribonucleic acid (DNA). ? DNA replicates to form (usually identical) copies of itself. ? DNA contains a code specifying what types of enzymes and other proteins are made in cells. ? DNA occasionally mutates, and the mutant forms specify altered proteins. ? A mutant enzyme is an ?inborn error of metabolism? that blocks one step in a bio- chemical pathway for the metabolism of small molecules. ? Traits are affected by environment as well as by genes. ? Organisms change genetically through generations in the process of biological evolution. ? Because of their common descent, organisms share many features of their genetics and biochemistry.

Semester 2: Biology Vocabulary Dominant - A comparative term, where one allele is expressed over the other True Breeding- The process of breeding of two organisms with an identical phenotype to procreate an organism with the same phenotype Recessive ? A comparative term, where one allele is not expressed over the other Sexual selection ? A process where mate is chosen based on certain characteristics or traits Homologous structures ? Structures that appear to be similar in different organisms, suggesting a common ancestry or an evolutionary origin. Selective breeding ? A process of breeding for a particular genetic trait Derived structures ? Structures that appear in the ancestor of a group or species, but do not appear in the other species.

Gregor Mendel Studied traits that occur in distinct forms. Developed true-breeding varieties When bred amongst themselves these plants produced offspring identical to the parent for that trait. Used mathematical analysis in his studies. Definitions Gametes: reproductive cells produced by sexually reproducing organisms. Two types: male gametes = sperm In plants: contained in pollen Female gametes = eggs In plants: contained in ovules which mature to seeds when fertilized Ovules contained in carpels Fertilization Fertilization: fusion of egg and sperm Self-fertilized: fusion of sperm and egg from same plant Cross fertilized: fusion of egg and sperm from two different plants Produced hybrids F1: first generation F2: second generation Mendel?s Model
