How much of my DNA do I share with my sister?

Full siblings generally share anywhere between around 2200 cM to around 3400 cM of DNA, or around 37.5–61%. The reason the answer varies from sibling pair to sibling pair is recombination: while both of them received 50% of their DNA from the same two people, the exact 50% they inherited is random.

Do family members share blood?

Brothers and sisters don't always share the same blood type. The genotype of both parents plays a role in defining the blood type. For instance, children of parents with the genotypes AO and BO may have the blood types A, B, AB, or O. Thus, siblings do not necessarily have the same blood type.

Are you more related to parents or siblings?

You're equally related to your parents and siblings - but only on average. It's often said you're equally genetically related to parents as (full) siblings: your 'relatedness' is a half. That means the chance that a bit of your own DNA is shared with your mother (by inheriting it from her) is 1/2.

Why do half-siblings only share 25%?

While we do get 50% of our DNA from each parent, we don't get the same 50% as our siblings. In general, there is about a 50% overlap between the DNA you got from your mom and the DNA your brother or sister got from that same mom. So you and your sibling share 50% of 50% of mom's DNA or 25%.
