How related are half-siblings?

Half-siblings are related through one shared parent, inheriting about 25% of their DNA on average, which is half the genetic material of full siblings (who share ~50%). They share DNA segments only from that one common parent, unlike full siblings who share DNA from both parents, making them genetically closer to first cousins or grandparents/grandchildren in terms of shared DNA percentage.

How closely related are half-siblings?

Half-siblings are moderately related, sharing about 25% of their DNA on average, which is half the genetic material they would share with a full sibling (50%) because they only share one biological parent. While they share the same amount of DNA as a grandparent or an aunt/uncle, the segments are usually different, meaning they share no fully identical DNA regions, only half-identical ones, making them distinct from full siblings genetically. 

Are half-siblings considered real siblings?

Yes, half-siblings count as siblings in everyday language and often legally, but they are specifically defined as sharing only one biological parent, making them genetically related but less so than full siblings (who share both).

Why do I only share 47% DNA with my dad?

It is not uncommon for Ancestry Composition Inheritance to report that a son or daughter inherited slightly more or less than 50% from each parent. This is because Ancestry Composition relies on the autosomes (chromosomes 1–22) and the X chromosome(s) to calculate Inheritance.

Which grandparent are you most related to?

You're generally most related to your maternal grandmother because you inherit her mitochondria (mtDNA) and get more X-chromosome DNA from grandmothers (maternal or paternal) compared to grandfathers (who pass a Y-chromosome), making her a genetic powerhouse in your ancestry, though chance and recombination mean individual relationships vary. Studies show most people feel closest to their maternal grandmother too, followed by maternal grandfather/paternal grandmother, then paternal grandfather, notes Psychology Today and National Institutes of Health (NIH) | (.gov).
