No, you are not 100% related to your parents in terms of DNA.
While you inherit genetic material from both your mother and father, the relationship isn't a complete 100% match. The reference material states you get approximately 50% of your DNA from each parent. That makes you ~50% related to each parent, but not 100% related to both of them combined in the sense of being an exact copy.
Here's a breakdown:
- 50% from Mom: You receive roughly half of your genetic material from your mother.
- 50% from Dad: Similarly, you inherit about half of your DNA from your father.
- Unique Combination: Your specific combination of DNA is unique to you, influenced by the shuffling of genes during the formation of egg and sperm cells (meiosis). This is why siblings, while also ~50% related to each parent, don't have the exact same DNA as you.
| Parent | Approximate % of DNA Shared |
|---|---|
| Mother | ~50% |
| Father | ~50% |
