Question

The Mendelian Inheritance Lab Pre-Lab Visit http://labcenter.dnalc.org/labs/mendeliangenetics/mendeliangenetics_d.html After Amanda finishes her introduction you will be able to explore the site. All the objects and pictures take you to other pages. Feel free to explore but the photos will be where you navigate to below. If you explore don’t get confused (not much of the instructions will apply to us in this virtual environment). I will provide you with the instructions to follow. Navigate to the follow pages (hover over the photos) and answer the questions while reading through everything. Click on Dominant Genes 1. What are the pure-bred genotypes in this activity? 2. What was the dominant phenotype of the Yy x Yy cross? Click on Genetic Inheritance 3. The idea that alleles are “randomly separated” into gametes is known as the Law of ___________. 4. What was the ratio of the Punnett outcome? Take the “How Unique Are You?” Quiz (go through all the traits. Pay attention to what they are, you will be reporting your traits in a class activity) 5. How many people took this quiz? 6. How many were like you? Watch the Color Vision video clip 7. Why is colorblindness found more often in men? 8. Which chromosome carries the colorblindness gene? Click on Making A Pedigree 9. What trait is being studied? 10. Who was it inherited from? 11. Who was affected in the first generation (this would be the first group of offspring)? 12. Who was affected in the second generations (this would be the grandchildren)? 13. Based on the results, is this an X-linked or Y-linked trait? Explain? Click on Mendelian Laws & Humans 14. What royal family is studied in this activity? 15. What disease was the family afflicted with? 16. How was is known that Beatrice & Alice were carriers? 17. The results of this pedigree is a classic example of what? 18. What was Queen Victoria’s genotype? Eye color….. 19. Of the eleven family members represented, how many had brown eyes? 20. Comparing the dominant pedigree to the recessive pedigree, what is the most obvious difference? 21. How many possible genes are involved in eye color determination?

Answer 1

any attempts? for example, I followed the first step, Click on Dominant Genes "What are the pure-bred genotypes in this activity" and I see two peas, one YY and the other yy, making these two the pure bred genotypes. I would imagine you just follow the directions and fill in the information from the website as appropriate.
