molecular genetics experiment: In what way do the percentages of yellow leaves vary between dishes on Day 2? How do you account for this difference? Compare the percentage of yellow seedlings in dish 2 on day 2 with the percentage on day 4. What is the difference? What experimental variable accounts for this difference? How can you account for the difference between the seedlings in dish 1? Is the yellow color genetically or environmentally controlled? How can environmental factors affect inheritance? (Use human height as an example.)

Explanation:

There were yellow seedlings in Dish #1 during the light phase and also during the dark in Dish #2. The difference in these results is likely due to the period of exposure to light.

There are more number of yellow seedlings on Day 4. This is probably because of being kept in the dark for a long period of time. Light intensity is the experimental variable that accounts for this difference in appearance.

The yellow color is being environmentally controlled since the parent phenotype was wildtype in this experiment. The environment has an effect on which genes are expressed in the organism, which in turn influences the phenotype observed.
