EVIDENCE FROM GENETICS II. Genetics After Mendel. Are all traits this simple?. Some phenotypes are due to the action of a single gene MOST, however, are polygenic Height Skin color Disease predisposition Heart disease High blood pressure Diabetes Cancer.

Fr. Gregor Mendel. Father of Genetics 1822 - 1884. Pre-Mendelian Ideas on Inheritance. Blending Homunculus. Homunculus. Why was Mendel Successful?. Good Research Organism (pea plant) * Small, easy to grow in large numbers * short life cycle  could test several generations

Chapter 5. Are You Only as Smart as Your Genes? Mendelian and Quantitative Genetics. 0. 1 The Inheritance of Traits. Offspring resemble their parents, but not exactly. Siblings resemble each other, but not exactly. How much is because of environment? How much is inherited?.

Chapter 14 MENDEL AND THE GENE IDEA . 1. Who were the two strong influences on Mendel’s education?. Doppler (physicist) Unger (botanist) What about Mendel’s monastery made it an ideal place to investigate genetics?. Why is the pea an ideal specimen for genetic studies?.

Exercise 3: Mendelian Genetics. Objectives (see page 27). Crosses Monohybrid Autosomal and Sex-Linked Dihybrid Autosomal Punnett Squares Scientific Method Chi-squared test Drosophila and Pea Genetics. When Meiosis goes afoul…. Karyotype: Trisomy 21. From Meiosis to Mendel.

Chapter 10. Patterns of Inheritance. What Is the Physical Basis of Inheritance?. Inheritance is the process by which traits are passed to the offspring Genes are sequences of nucleotides at specific locations on chromosomes

Jeopardy. Name the three types of chromosomes . Sex Chromosomes Autosomal Chromosomes Homologous Chromosomes. Chromosomes for 100 . Back. Chromosomes for 200 . How many chromosomes are in the body cells of a dog that has a haploid number of 39? . 78 chromosomes. Back.

Chapter 11 Introduction to Genetics. 11-3: Exploring Mendelian Genetics Objectives: Explain the principle of independent assortment. Describe the inheritance patterns that exist aside from simple dominance. Explain how Mendel’s principles apply to all organisms. Independent Assortment.

Patterns of Inheritance. By observing how traits are passed to the next generation, how can the inheritance patterns be used to understand the principles of heredity? . Use of Garden Pea for Genetics Experiments. Stamens (male) produce pollen. Carpel (female) produces eggs.

Chromosomal Basis of Inheritance. Chapter 3. Chromosomes and Cellular Reproduction. Eukaryote Chromosomes. Multiple linear chromosomes Many have two of each type Diploid zygote Fusion of two haploid gametes Called homologous chromosomes Autosomes Sex chromosomes. Eukaryote Chromosomes.

Linkage, Recombination and Eukaryotic Mapping. Outline. Introduction Complete Linkage compared to independent assortment Crossing over with linked genes “coupling and repulsion” gene arrangements Predicting outcomes with linked genes Gene mapping with recombination frequencies

Mitosis/Meiosis How are they different?. Crossing over. The exchange of DNA between the chromatid arms on homologous pairs is called ________________. This type of cell division used by bacteria to reproduce. Binary fission.

The work of Gregor Mendel. Austrian monk Father of Genetics Previous views of Inheritance Blending Spermists Ovists. “Father of Genetics”. Mendel performed breeding experiments with garden peas Found mathematical patterns of inheritance

Introduction to Genetics & Gregor Mendel. Stuff you may not know…. All living things contain deoxyribonucleic acid ( DNA ). DNA, in humans, is located in the nucleus of all of our cells.* The DNA is arranged in the nucleus as organized packets known as chromosomes .

Mendel’s Laws of Inheritance.

Chapter 15 The Chromosomal Basis of Inheritance. Timeline. 1866- Mendel's Paper 1875- Mitosis worked out 1890's- Meiosis worked out 1902- Sutton, Boveri et. al . connect chromosomes to Meiosis. Sutton. Developed the “Chromosome Theory of Inheritance”.

THE DIHYBRID CROSS. Studying the inheritance of two characters simultaneously. © 2007 Paul Billiet ODWS. Mendel’s peas. © 2007 Paul Billiet ODWS. Combinations. © 2007 Paul Billiet ODWS. Is the inheritance of one character affected by the inheritance of another?.

Mendel’s Laws of Heredity. Why we look the way we look. What is heredity ?. The passing on of characteristics (traits) from parents to offspring Genetics is the study of heredity. Mendel used peas. They reproduce sexually
