How can offspring in asexual reproduction be slightly different even though they are very similar?
Answer and explanation
Correct answer: Due to small errors while copying genetic material
The governing concept is that asexual reproduction usually produces genetically similar offspring from one parent, but copying DNA is not perfectly error-free. Occasional small mutations or copying errors can create differences in the genetic material. Environmental effects may also influence appearance, but the biological source of inherited variation here is copying error. Option A is correct; B describes sexual reproduction, C is false because chromosomes are present, and D is not a genetic explanation.
