The concept you described, often referred to as the "grandfather paradox," is a popular topic in science fiction when discussing time travel. However, it is important to note that time travel, as far as our current scientific understanding goes, is purely speculative and has not been proven possible.
If we were to entertain the hypothetical scenario you described, it would indeed create a paradoxical situation. If you traveled back in time and became your own ancestor by conceiving your father, it would introduce a loop in your family tree. In this scenario, your genetic makeup would be affected, as you would be both your own ancestor and descendant.
The exact consequences and implications of such a paradox are uncertain and would largely depend on the rules and mechanisms of time travel in this hypothetical scenario. It would raise questions about the stability of the timeline and the nature of causality. It is possible that such a paradox could lead to inconsistencies and logical contradictions, challenging our understanding of genetics and the concept of individual identity.
However, it's important to reiterate that time travel is currently speculative and purely theoretical. The consequences of time travel, especially regarding personal genetics and paradoxes, remain in the realm of imaginative speculation and are not grounded in scientific evidence or observation.
