Final Answer:
The incorrectly matched pair is E. gene B carpel formation, whorl 4.
Step-by-step explanation:
The carpel formation in flowering plants is typically associated with the fourth whorl, but E.gene B is actually responsible for petal formation in the second whorl. Carpel formation is controlled by gene C in the fourth whorl. Therefore, option E is the mismatched pair.
Understanding the genetic control of floral organ development is essential in plant biology. The coordination of different genes in specific whorls regulates the formation of sepals, petals, stamens, and carpels, ultimately determining the structure and function of flowers. Recognizing the correct gene-whorl associations is crucial for studying plant development and manipulating floral traits for agricultural and horticultural purposes.
In conclusion, the mismatched pair in this context is option E, where gene B is incorrectly associated with carpel formation in the fourth whorl. This knowledge contributes to our understanding of the genetic mechanisms underlying floral development, with implications for plant breeding and cultivation practices.
