Answer 1

Answer:

Reproduction is the creation of a DNA copy. Cells use chemical reactions for DNA replication or to make copies of itself. The process of copying DNA will have some variations each time. Thus the DNA copies generated will be similar but may not be identical to the original.

Answer 2

Answer:

The DNA copying mechanism, also called the DNA replication processes, are highly precise, but they are not completely accurate. Each time when the DNA is copied, some changes or mistakes might take place in formation of the new DNA strand. These mistakes account for the variations that occur amongst the individuals in a population. In sexual reproduction, these changes increase in rate of occurrence due to involvement of two individuals with different patterns of accumulation of variations. The variations hence created, are unique in nature. Thus, the DNA copies generated are similar, but not identical to the original.
