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

Surface Area to Volume Ratio and Karyotypes Surface Area= Area of each side of an object combined (Ex= Cube has 6 sides so the surface area would be the area of each side added all together) Volume= The amount of space that an object occupies, length x width x height Surface area to volume ratio can be described as the bigger something is or the more volume, the less surface area. On the other hand, the smaller something is or the less volume, then the more surface area.

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

You will learn how to collect data from F1 and F2 generations and analyze the results from a monohybrid, dihybrid, or sex-linked cross. Objectives Use chi-square to analyze data Understand the life cycle of fruit flies Investigate the independent assortment of two genes and determine whether the two genes are autosomal or sex-linked using a multi-generation experiment Introduction

Environment

The last ice age produced many different species mainly because of vicariance events; the glaciers physically separated populations from each other. Sympatry: populations that live close enough to interbreed Gene flow prevents speciation in sympatric populations A mating between a tetraploid individual and a diploid individual produces: triploid individuals: which likely produce nonviable gametes with an uneven number of chromosomes All polyploid individuals contain more than two haploid sets of chromosomes

Overview: Locating Genes Along Chromosomes ? Mendel?s ?hereditary factors? were genes, though this wasn?t known at the time. ? The location of a particular gene can be seen by tagging isolated chromosomes with a fluorescent dye that highlights the gene. Concept 12.1 Mendelian inheritance has its physical basis in the behavior of chromosomes ? The chromosome theory of inheritance states: ? Mendelian genes have specific loci (positions) on chromosomes ? Chromosomes undergo segregation and independent assortment. ? The behavior of chromosomes during meiosis was said to account for Mendel?s laws of segregation and independent assortment. Morgan?s Experimental Evidence & Choice of Experimental Organism
