How many from your father? 3. What are homologous chromosomes? 4. How are sex chromosomes different? 5. 6. 7. 8. 9. 10. How many chromosomes do sperm and egg cells have? What is genetic recombination? Which chromosomes are passed on intact? What is a phenotype? Can we alter traits we inherited? What about psychological traits? What do geneticists do? Genetics – main ideas 0. Examples of Single­Gene (Mendelian) Behavioral Traits 1. Polygenic Characteristics Genetics quiz Where is your DNA? 0. only in your gonads 1. in all your cells 2. only in your blood Who has the exact same DNA as you do? 3. all human beings 4. your children 5. only you What is a gene? 6. the basic unit of hereditary information 7. a cell in the human body that causes disease 8. a protein found in the human body What is a genome? 9. the part of a cell that makes proteins 10. an organism's complete set of hereditary information 11. all the cells in an organism Genetics quiz What's the relationship between genes and chromosomes? 12. Genes are found in every cell; chromosomes are found only in sex cells. 13. Chromosomes determine gender; genes determine other cellular functions. 14. Chromosomes are compact storage units for genes. How much of your DNA is needed in order to conduct a genetic test? 15. a single cell 16. a teaspoon 17. a tissue sample If you have a gene for a disease, will you get that disease? 18. yes 19. only if both your parents have the gene 20. it depends Genetics quiz What is the link between genes and complex social behaviors such as shyness or intelligence? 21. Behavior can represent a complex link between genes and environment. 22. Genes determine specific behaviors in every individual. 23. Genes have no influence on behavior, only on physical traits. 0. 11. Artificial breeding enables selecting and breeding desirable traits.
