Genetic modifications interfere with conventional genetic processes. They enhance genetics while genetic sexual reproduction occurs naturally. In essence, modifications are artificially altered whereas sexual reproduction is a natural process.
The variations caused by genetic modification lead to alterations in the organism's genome. Such changes express traits in ways that differ from the typical. These variations can cause genetic mutations that may be passed down generations.
In the case of sexual reproduction, the organism's genome remains unchanged. Here, only an exchange occurs between the alleles inherited from each parent, and this does not result in mutations.
Based on the lessons regarding the Principle of Fossil Correlation, it asserts that rock layers containing identical fossil groupings are reflective of the same geological age.
