Lab No. 18: Biochemical Genetics: Smooth Peas Wrinkled Peas
Data Presentation:
The diagram of cotyledon for smooth and wrinkled pea is attached to the next page.
The table of starch presents is below:
Type of Pea
Starch Present? (Color change)
Smooth
Yes (Dark blue)
Wrinkled
No (No change)
Conclusion
Smooth pea is dominant than wrinkled one, hence we can say the letter of allele which controls this characteristics is S. 'SS' and 'Ss' for smooth, and 'ss' for wrinkled.
In the first experiment, we observed the cotyledon of both smooth and wrinkled pea that contains starch or not using iodine solution. Both smooth and wrinkled pea changed its color to dark-blue, and it means that they both contain starch. However, the shape was slightly different from each other; the smooth one had a brighter color and has a regular round shape. However, the wrinkled one was much darker and does not have a regular shape. This result might be caused by some mistakes, which were the amount of iodine solution and the thickness of cotyledon.
