If a colour change occurs only during lifetime due to sunlight why will it not give a lasting contribution to evolution?
Answer and explanation
Correct answer: Because it is not recorded in hereditary information of gametes
The governing concept is the difference between acquired and inherited variation. A colour change caused by sunlight affects the organism during its lifetime, but it does not normally alter the DNA of its gametes. Since gametes carry hereditary information to offspring, the change is not transmitted and cannot accumulate through generations. Therefore option A is correct; sunlight does not erase all genes, and the change does not pass to every child.
