Chapter 1 Introduction to Genetics COMPREHENSION QUESTIONS Matching For questions 1-8, match the research focus to the subdiscipline of genetics inwhich that phenomenon is primarily studied. 1. Evolution (c) a. Transmission genetics 2. Chemical nature of gene (b) b. Molecular genetics 3. Gene regulation (b) c. Population genetics 4. Arrangement of genes onchromosomes (a) 5. Gene mapping (a) 6. Differences in allele frequencies in wetand dry environments (c) 7. Differences in gene expression in wet and dry environments (b) 8. Translation (b) True/False 9. Humans first applied genetics to the domestication of plants and animals between approximately 10,000 and 12,000 years ago. (T) 10. The theory of pangenesis states that all living organisms are composed ofcells. (F) 11. Many human traits, such as skin and hair color, exhibit blending inheritance, in which genetic information is mixed and is not separated in future generations. (F) 12. Bacteria and viruses can be used to study genes and inheritance, even though they are structurally and metabolically different from animal and plantcells. (T) 13. Some viruses have RNA as their genetic information. (T) 14. Charles Darwin accurately described the laws of inheritance in his landmarkbook, On the Origin of Species. (F) 15. Albinism requires a mutation in all of the genes that control the synthesis and storage of melanin. (F)
