CHAPTER 15THE CHROMOSOMAL BASIS OFINHERITANCE Copyright ? 2002 Pearson Education, Inc., publishing as Benjamin Cummings Section A: Relating Mendelism to Chromosomes1. Mendelian inheritance has its physical basis in the behavior ofchromosomes during sexual life cycles2. Morgan traced a gene to a specific chromosome3. Linked genes tend to be inherited together because they are located on thesame chromosome4. Independent assortment of chromosomes and crossing over produce geneticrecombinants5. Geneticists use recombination data to map a chromosome?s genetic loci

Ch 14: Mendel and the Gene Idea Overview: Drawing from the Deck of Genes What genetic principles account for the passing of traits from parents to offspring? The ?blending? hypothesis is the idea that genetic material from the two parents blends together (like blue and yellow paint blend to make green) The ?particulate? hypothesis is the idea that parents pass on discrete heritable units (genes) This hypothesis can explain the reappearance of traits after several generations Mendel documented a particulate mechanism through his experiments with garden peas Concept 14.1: Mendel used the scientific approach to identify two laws of inheritance Mendel discovered the basic principles of heredity by breeding garden peas in carefully planned experiments

Chapter 14 Mendel and the Gene Idea Overview: Drawing from the Deck of Genes What genetic principles account for the transmission of traits from parents to offspring? One possible explanation of heredity is a ?blending? hypothesis The idea that genetic material contributed by two parents mixes in a manner analogous to the way blue and yellow paints blend to make green An alternative to the blending model is the ?particulate? hypothesis of inheritance: the gene idea Parents pass on discrete heritable units, genes Gregor Mendel Documented a particulate mechanism of inheritance through his experiments with garden peas Figure 14.1 Concept 14.1: Mendel used the scientific approach to identify two laws of inheritance Mendel discovered the basic principles of heredity

Mendelian Genetics All Materials ? Cmassengale? 1862 1868 1880 Genetic Terminology: Trait?- any characteristic that can be passed from parent to offspring Heredity?- passing of traits from parent to offspring Genetics?- study of heredity Alleles?- two forms of a gene (dominant & recessive) Dominant?- stronger of two genes expressed in the hybrid; represented by a?capital letter (R) Recessive?- gene that shows up less often in a cross; represented by a?lowercase letter (r) Genotype?- gene combination for a trait (e.g. RR, Rr, rr) Phenotype?- the physical feature resulting from a genotype (e.g. tall, short) Homozygous?genotype - gene combination involving 2 dominant or 2 recessive genes (e.g. RR or rr); also called?pure?
