The statements about the function of class a, b, and c genes and developmental outcome of the flower structure is Class B genes combined with class A genes results in petal development.
Option A is correct
When class A genes are inactivated, class C genes will dominate the developmental process is not correct because while class C genes will be the dominant influence, there will still be some development of sepals, as class A genes are not the sole determiners of sepal development.
Class A gene products and class C genes are antagonistic to each other is not correct as class A and C genes have opposing effects on the development of floral organs, they are not strictly antagonistic. In fact, they need to interact with each other in a balanced way for proper flower development.
Complete question:
which of these statements about the function of class a, b, and c genes and developmental outcome of the flower structure is correct?
A. Class B genes combined with class A genes results in petal development.
B. When class A genes are inactivated, class C genes will dominate the developmental process.
C. Class A gene products and class C genes are antagonistic to each other.
D. Class B genes combined with class C genes results in stamen development.
E. Class B genes can dominate the structure when class A genes are absent.-
