Genetics Has Been Investigated Using Many Different Approaches. Genetics Has a Profound Impact on Society. GENETICS, TECHNOLOGY, AND SOCIETY. The Frankenfood Debates: Genetically Modified Foods. Chapter Summary. Key Terms. Problems and Discussion Questions. Selected Readings. 2. Mitosis and Meiosis. Cell Structure Is Closely Tied to Genetic Function. Chromosomes Exist in Homologous Pairs in Diploid Organisms. Mitosis Partitions Chromosomes into Dividing Cells. The Cell Cycle Is Genetically Regulated.

Meiosis Is Critical to the Successful Sexual Reproduction of All Diploid Organisms. Electron Microscopy Has Revealed the Cytological Nature of Mitotic and Meiotic Chromosomes. Chapter Summary. Key Terms. Insights and Solutions. Problems and Discussion Questions. Selected Readings. 3. Mendelian Genetics. Mendel Used a Model Experimental Approach to Study Patterns of Inheritance. The Monohybrid Cross Reveals How One Trait Is Transmitted from Generation to Generation. Mendel's Dihybrid Cross Generated a Unique F2 Ratio. The Trihybrid Cross Demonstrates that Mendel's Principles Apply to Inheritance of Multiple Traits. Mendel's Work Was Rediscovered in the Early Twentieth Century. Independent Assortment Leads to Extensive Genetic Variation. Laws of Probability Help to Explain Genetic Events. How Mendel's Peas Become Wrinkled: A Molecular Explanation. Chi-Square Analysis Evaluates the Influence of Chance on Genetic Data. Pedigrees Reveal Patterns of Inheritance in Humans. Chapter Summary. Key Terms. Insights and Solutions. Problems and Discussion Questions. Selected Readings. 4. Modification of Mendelian Ratios. Alleles Alter Phenotypes in Different Ways. Geneticists Use a Variety of Symbols for Alleles. Neither Allele Is Dominant in Incomplete, or Partial, Dominance. In Codominance, the Influence of Both Alleles in a Heterozygote Is Clearly Evident. Multiple Alleles of a Gene May Exist in a Population. Lethal Alleles Represent Essential Genes. Combinations of Two Gene Pairs with Two Modes of Inheritance Modify the 9:3:3:1 Ratio. Phenotypes Are Often Affected by More than One Gene. Complementation Analysis Can Determine if Two Mutations Causing a Similar Phenotype Are Alleles. X-Linkage Describes Genes on the X Chromosome. In Sex-Limited and Sex-Influenced Inheritance, an Individual's Sex Influences the Phenotype. Phenotypic Expression Is Not Always a Direct Reflection of the Genotype. Extranuclear Inheritance Modifies Mendelian Patterns. GENETICS, TECHNOLOGY, AND SOCIETY. Improving the Genetic Fate of Purebred Dogs. Chapter Summary. Key Terms. Insights and Solutions. Problems and Discussion Questions. Selected Readings. 5. Sex Determination and Sex Chromosomes. Life Cycles Depend on Sexual Differentiation.

Until 1944, Observations Favored Protein as the Genetic Material. Evidence Favoring DNA as the Genetic Material Was First Obtained During the Study of Bacteria and Bacteriophages. Indirect and Direct Evidence Supports the Concept that DNA Is the Genetic Material in Eukaryotes. RNA Serves as the Genetic Material in Some Viruses. The Structure of DNA Holds the Key to Understanding Its Function. Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid. Alternative Forms of DNA Exist.
