Problem
The Activate gene codes for the ACT protein. ACT is an activator protein (transcription factor) and helps regulate expression of genes involved in plant growth.
ACT binds compound X; when compound X is available and binds to ACT, a conformational change occurs in ACT allowing it to function.
You have plants that are homozygous wildtype for the Activate gene. As well, you have plants that are heterozygous for a mutation in the Activate gene. This is a nonsynonymous mutation in the region of Activate that encodes the compound X binding region of the ACT protein.
You raise plants of each genotype in two different environments, one environment in which compound X is absent and one in which there are high amounts of compound X
Do the following:
1. Draw a norm of reaction graph for this study if Activate was haplosufficient.
2. Draw the norm of reaction graph for this study if Activate was haploinsufficient.
3. Explain the two graphs and differences between them.
