An African butterfly that is green in the summer turns brown in the fall thanks to a temperature-controlled genetic switch.This best illustrates that genes are

A) dizygotic.
B) self-regulating.
C) epigenetic marks.
D) protein molecules.

Question

Tisha Yazzie · Accepted Answer

Final Answer : B, Explanation :  The fact that the African butterfly's gene can switch between producing green pigment in the summer and brown pigment in the fall based on temperature demonstrates that the gene is self-regulating.Answer: CEpigenetic marks refer to modifications to DNA that can influence gene expression without changing the underlying genetic sequence. While the African butterfly's color change is not specifically due to epigenetic marks, it is an example of an environmental trigger (temperature) affecting gene expression, which is similar to the way epigenetic marks can influence gene expression.Therefore, both B and C are acceptable answers.

A) dizygotic.
