Question

is an offspring is exactly similar to its parent? why or why not

Answer 1

An offspring born of sexual reproduction will have characteristics of both parents not just one so they will be similar to both parents but not an identical copy

Answer 2

We know that reproduction occurs by two means of sexual and a-sexual reproduction.

Since, offspring may or may not exactly similar to its parents.

Offspring generated by a-sexual reproduction have chance of being exactly similar, but it may not.

Variability exist in sexual reproduction mainly. This is only because of inappropriate DNA copying.
