Definition
While reproduction, the DNA of the parent cell is copied, that is why we appear similar to our parents.
In Asexual Reproduction
DNA Copying is simple, and it occurs through mitosis (thus, the same number of chromosomes). And thus, the daughter cell is genetically identical (except for any Variations)
In Sexual Reproduction
It requires both male and female gametes, and division happens through meiosis (half of the chromosomes). There is the combination of the chromosomes in the new cell after fertilization. The new cell inherits traits.

Why is there DNA Copying? ? While reproduction, the DNA of the parent cell is copied, that is why we appear similar to our parents.
Why is the daughter cell genetically identical to the parent cell which reproduces asexually? ? DNA Copying is simple, and it occurs through mitosis (thus, the same number of chromosomes). And thus, the daughter cell is genetically identical (except for any Variations)
