What parent determines blood type?

ABO blood type is inherited just like any other trait. Every person carries two genes, or alleles, for each trait. One ABO allele is inherited from the father (who passes on one of his two) and the other is inherited from the mother (who passes on one of her two).

Is blood type inherited from the father?

Blood type, like all phenotypic traits, is rooted in your DNA. When you were conceived, you received one variation of blood type, or “allele,” from your mother and another from your father. If you inherited a Type A allele from your mother and a Type B allele from your father, you would have Type AB blood.

Can siblings have different blood types?

No, siblings don’t necessarily have the same blood type. It depends on the genotype of both the parents for the gene determining the blood type. E.g. Parents with the genotype AO and BO can have offspring with blood type A, B, AB or O.

How do I find out my blood type without a test?

Without drawing blood A person may be able to use a saliva sample to test for their blood type. Around 80% of people produce the relevant antigens in their saliva. According to 2018 research , if a person secretes these antigens in their saliva, a dried saliva sample can reliably indicate their blood type.

How can I check my blood type at-home?

In at-home blood typing tests, they typically ask that you prick your finger with a lancet and put drops of your blood on a special card. After putting the blood on the card, you can observe the areas where blood clumps or spreads out, and then match those reactions to an included guide.

What’s the healthiest blood type?

Type O negative red blood cells are considered the safest to give to anyone in a life-threatening emergency or when there’s a limited supply of the exact matching blood type. That’s because type O negative blood cells don’t have antibodies to A, B or Rh antigens.
