Question

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. DNA
b. self-regulating
c. chromosomes
d. protein molecules
e. evolving

Answer 1

Genes are self-regulating and can respond to external cues to regulate the expression of traits.

Step-by-step explanation:

The African butterfly that changes color based on temperature has a temperature-controlled genetic switch. This means that certain genes are activated or deactivated depending on the temperature, causing the butterfly to change color.

This example illustrates that genes are self-regulating, as they have the ability to respond to external cues and regulate the expression of traits.
