Which parent determines blood type?

Neither parent alone determines blood type; it's a genetic combination where each parent contributes one allele (gene version) for the ABO system and one for the Rh factor (positive/negative), with dominant genes (like A, B, or Rh+) overriding recessive ones (O or Rh-) to form the final blood type. You inherit one set of blood type instructions from your mother and another from your father, and how these two sets mix creates your blood type (A, B, AB, or O, and +/-).

Can a child have a different blood type than both parents?

Yes, a child can have a different blood type than both parents because blood type is determined by inheriting one gene (allele) from each parent, and combinations of dominant (A, B) and recessive (O) genes create different possibilities, like parents with A and B types potentially having O or AB children, or even rarer genetic situations like chimerism. 

What determines blood type, mom or dad?

Your ABO blood type is determined by whether you inherited an A, B or O from each of your parents. Since you get one of these blood type “codes” from each parent, the genetic makeup of your blood type is a combination of two of the above three blood type options (A, B, or O).

Does the blood of a child come from the father or the mother?

Well, your blood is definitely all your own--your body produced it. But because of how the genetics of blood type works, it could seem like you have your mom's blood type, your dad's blood type, or a mix of the two. For every gene, you get two copies -- one from your mom and one from your dad.

Which blood type would the man never be the father of a child?

If the child is A or AB one of the individuals cannot be the parent. An O and B crossing can not produce an A or AB child. An AB with an O can produce A children or B children but not O.

Do siblings all have the same blood type?

No, siblings do not always have the same blood type; it's common for them to have different blood types because each child inherits unique combinations of ABO and Rh genes from their parents, leading to varied outcomes even from the same parents. While they share about 50% of their DNA, the specific combination of A, B, and O alleles, plus the Rh factor (positive or negative), can result in different blood types, similar to how eye or hair color can vary.
 

What was Jesus rare blood type?

Yet today, science shows us that what these miracles have in common is the blood is all AB. A rare blood type. Furthermore the relics associated with the Lord's passion and death, the Turin Shroud and the Sudarium of Oviedo both contain traces of blood and were also of the same rare blood type.

What was Marilyn Monroe's blood type?

Marilyn Monroe's blood type is widely cited as AB, often mentioned alongside other famous figures like JFK in discussions about the AB blood type personality theories. While blood type personality theories aren't scientific, many sources connect her to AB, suggesting traits like being intuitive, passionate, and sometimes conflicted.
 

Which blood type was Einstein?

Said to be the best physicist of the twentieth century, Albert Einstein has been treated as a strange person due to his unbelievable behavior and going at his own pace.It was caused by his blood type "B"!

Can a person's blood type change?

Yes, a person's blood type can change, but it's very rare and usually happens due to major medical interventions like a bone marrow transplant (where you adopt the donor's blood type) or in very specific, temporary cases of severe illnesses like certain types of leukemia, where the body stops producing certain antigens, or after massive transfusions. Normally, blood type is genetically determined and stays the same for life. 

What are the top 3 rarest blood types?

Most Rare Blood Type

• AB-negative – 1 %
• B-negative – 2 %
• AB-positive – 4 %
• A-negative – 6 %
• O-negative – 7 %
• B-positive – 11 %
• A-positive – 32 %
• O-positive – 40 %

Can a child be O blood type if parents are not?

Yes, a child can have type O blood even if neither parent is type O, provided both parents carry the recessive 'O' gene (meaning they are type A, B, or AB) and pass it to the child, making the child OO. For a child to be Type O (OO), they must inherit an 'O' allele from each parent, so parents with A and B types can have an O child if they are AO and BO genotypes, respectively, but parents who are type AB (genotype AB) generally can't have an O child as they don't carry the 'O' allele to pass on. 

Do twins have the same blood type?

Identical twins almost always have the same blood type because they share nearly identical DNA, while fraternal twins can have different blood types, just like any other siblings, as they develop from separate eggs and sperm. The rare exception for identical twins having different blood types involves a very uncommon genetic mutation or blood chimerism from fused embryos, but for practical purposes, identical twins share blood types. 

What two blood types should not have babies together?

The main concern isn't specific ABO blood types (like A, B, O) but rather the Rh factor, where an Rh-negative mother and Rh-positive father can have a baby at risk for Rh incompatibility, potentially causing problems if the mother's body develops antibodies against the baby's Rh-positive blood. While ABO issues can occur, Rh incompatibility (Rh- mother, Rh+ baby) is the most common type, managed with Rh immunoglobulin shots (RhoGAM) to prevent antibody formation and ensure healthy pregnancies. 

What is the Bombay blood type?

H antigen deficiency is known as the "Bombay phenotype" (h/h, also known as Oh) and is found in 1 of 10,000 individuals in India and 1 in a million people in Europe.

What blood type is Leonardo DiCaprio?

Leonardo DiCaprio's blood type is reported to be Type B, often mentioned in lists of celebrities with this blood type, though specific confirmation from a highly reliable source isn't easily found, it's a consistent detail in some public-facing personality analyses. 

What disability does Marilyn Monroe have?

The Illness Trajectory in Marilyn Monroe's Psychological Autopsy: From Autism Spectrum Disorder to Borderline Personality Disorder and Bipolar Disorder with Catatonia.

What blood type was Princess Diana?

While Princess Diana's exact blood type isn't widely publicized, there's speculation and interest in the royal family's potential prevalence of Rh-negative blood, with her Spencer lineage linked to "blue bloods," but official confirmation of her specific type (like A, B, O, or AB, plus positive or negative) isn't readily available in public records, though some genealogical sites suggest Rh-negative might run in her Spencer family. 

What is the miracle blood type?

The "miracle blood type" refers to Type AB, consistently found in scientific analyses of various Eucharistic miracles (consecrated hosts turning to flesh/blood) and relics (like the Shroud of Turin, Sudarium of Oviedo) believed to be connected to Jesus Christ, symbolizing universal reception for believers. While this rarity (AB is ~5% of people) and consistency suggest a miracle to many, some scientists point out that bacteria also express AB antigens, complicating definitive proof without advanced DNA analysis, though modern methods aim to distinguish human from bacterial sources. 

What is the oldest blood type on Earth?

While the exact timeline is debated, scientific evidence suggests blood type A likely evolved first, with B and O developing later from mutations, though O is often considered the most "ancestral" in terms of being a baseline lack of A/B antigens and common in ancient populations, with type AB being the most recent, arising from the mixing of A and B groups. 

Whose DNA did Jesus have?

Jesus had human DNA from his mother, Mary, and divine DNA from God the Father, with theologians explaining that God miraculously provided the male chromosomes (Y chromosome) and the "life principle" to form Jesus's human body without a human father, making him both fully human and fully divine. While Mary provided the "substance" of his human nature, God ensured the creation of a unique, sinless human being with both divine and human qualities, combining Mary's genetic contribution with a divine one for the male half. 

Which sibling is the healthiest?

Birth order effects on health evolve over the life-cycle. Firstborns have worse health at birth. Younger siblings are more often hospitalized for conditions related to risky behavior. At old age older siblings are more often treated for metabolic syndromes.

Do all kids have their father's blood type?

No, a child doesn't always have their father's blood type; blood type comes from a combination of genes from both parents, so a child can have their mother's type, their father's type, or a unique mix (like AB or O). You inherit one ABO gene and one Rh factor gene from each parent, leading to different combinations, with dominant A/B and Rh+ genes often masking recessive O and Rh- genes.
 

Why don't siblings share 100% DNA?

Siblings don't share 100% DNA because they inherit a random 50% from each parent, not the exact same 50%, and their parents' chromosomes get shuffled (recombination) before being passed down, creating unique combinations, like drawing different hands from the same deck of cards, leading to about 50% shared DNA on average, not identical copies.
