Create a floral mutants – think ABC Model. Show (draw) how the gene expression changes as well as the resulting phenotypes. Then explain why SEUSS is a good example of Eukaryotic gene regulation.

Step 1
- Class A genes promote sepal identity. - Class A and B genes together promote petal identity. - Class B and C genes together promote stamen identity. - Class C genes promote carpel identity. Show more…

Using the ABC model of flower formation by Meyerowitz, create a flower with sepals and petals only by providing the gene(s) involved for the formation of the specific floral parts and indicate which gene(s) must mutate to get this phenotype.

Make a sketch of a simplified flower with all four organs, and indicate how the pattern of expression for just two genes (e.g., " $D "$ and $^{*} E^{\prime \prime}$ ) could, hypothetically, regulate the development of each organ. Consider that what's important is whether a gene is on or off and that a structure can be specified when neither gene is expressed.
When scientists found where A, B, and C genes were expressed in developing Arabidopsis flowers and the expression pattern of A gene was changed in C function mutant, these two data were considered as strong supports for the ABC model. Explain why.
