Biology 3201 Unit 3 GENETICS; Part 1 Mendelian & Modern Genetics ______Chapter 16 Suggested Time: 10 Hours of 44 hours for all of Unit 3

Genetics: Mendelian 1. Define the terms heredity and genetics. 2. Explain Mendel’s concept of unit characters and describe the unit theory of inheritance 3. explain the meaning of the following terms: (i) trait (viii) recessive (ii) purebred (ix) gene (iii) P generation (parent (x) allele generation) (xi) homozygous (iv) F1 and F2 generation (xii) heterozygous (first and second filial (xiii) product rule generation) (xiv) punnett square (v) hybrid (xv) genotype (vi) monohybrid (xvi) phenotype (vii) dominant 4. Explain how Mendel’s experiments support: a. principle of dominance b. law of segregation c. law of independent assortment 5. Predict the outcome of monohybrid and dihybrid crosses using Punnett Square or Product Rule 6. Predict the genotypic and phenotypic ratios in one factor (monohybrid) and two-factor (dihybrid) crosses 7. Explain the meaning of the following terms: (i) incomplete dominance (ii) co-dominance (iii) multiple alleles 8. Predict the outcome of monohybrid crosses for incomplete and codominance 9. Demonstrate the inheritance of traits governed by multiple alleles by predicting the genotypic and phenotypic ratios in crosses involving human blood types (ABO groups) 10. Explain the significance of a test cross 11. Use a test cross to determine the unknown genotype of a dominant organism

Genetics: Modern Ideas

12. Explain how the work of Gregor Mendel and Walter Sutton led to the Chromosome Theory of Inheritance 13. State and explain the Chromosome Theory of Inheritance 14. Describe Morgan’s experiments with Drosophila and explain how his observations supported the Chromosome Theory of Inheritance 15. Explain the concepts of gene linkage (linked genes) and crossing-over. 16. Explain how the discovery of gene linkage affected man’s understanding of Mendel’s Law of Independent Assortment 17. State the Law of Independent Assortment in modern terms 18. Outline, in general terms, the Gene-chromosome Theory of Inheritance 19. Define sex-linkage (inheritance of certain characteristics (red-green colour blindness, hemophilia, muscular dystrophy) 20. Explain why sex-linked effects are more common in males than females 21. distinguish between genotypes and phenotypes evident in autosomal and sex-linked inheritance 22. Explain the influence of polygenic traits on inheritance patterns. 23. Predict the outcome of monohybrid crosses for sexlinked traits 24. Analyze and interpret models of human karyotypes (Conduct Karyotyping Lab).
