No one has been able to explain where people with the Rh-negative blood type people came from. Most, familiar with blood factors, admit that these people must be the result of a random mutation, if not descendants of a different ancestor.

People With RH Negative Blood Have THIS In Common! - David ...

Most humans have RH positive blood, meaning they carry a gene originating from the rhesus monkey.. Humans are believed to have evolved from a similar ancestor. But 10-15% of people do not carry this gene, which means there is a small amount of people on the planet who are RH negative.Such people lack not only that rhesus monkey gene but the proteins that …

Can mutations change blood type from parents to offspring ...

One of the parents is genotypically heterozygous for the B-blood type (BO), but they have a promoter modification (like methylation of the promoter) that silences phenotypic expression of B-type antigen. So, they have the gene for B-type blood, but they don't express it because their B-allele is "turned off" in their erythropoietic tissue.

What Is the Golden Blood Type? - MedicineNet

The golden blood type or Rh null blood group contains no Rh antigens (proteins) on the red blood cell (RBC). This is the rarest blood group in the world, with less than 50 individuals having this blood group. It was first seen in Aboriginal Australians. The worry with the golden blood group is that the donations of Rh null are incredibly scarce and difficult to …

Some Think This Blood Type Has An Alien Origin; Do You ...

Some believe Rh-negative blood is simply a mutation that came about at some unknown time in our evolution. But, as strange as it sounds, others have speculated at the possibility that it may have come from an alien species that interbred with humans or engineered us in some way, producing a hybrid bloodline.

About Hemophilia

Mutations in the FVIII gene cause hemophilia A. Mutations in the FIX gene cause hemophilia B. Proteins made by these genes have an important role in the blood clotting process. Mutations in either gene keep clots from forming when there is an injury, causing too much bleeding that can be difficult to stop.

Understanding Genetics

What makes us different are the different versions of these genes. For example, we all have the blood type gene, ABO. What gives us different blood types is that this gene comes in three different versions: A, B, and O. In a simple world, the three versions would give three blood types and a child would have one of the blood types of the parents.

The molecular basis of the ABO blood group system was elucidated in 1990. 7 The gene encodes a glycosyltransferase, which transfers N-acetyl D-galactosamine (group A) or D-galactose (group B) to the nonreducing ends of glycans on glycoproteins and glycolipids.The group O phenotype results from inactivation of the A1 glycosyltransferase gene, and the …

Sickle cell disease - Wikipedia

Sickle cell disease (SCD) is a group of blood disorders typically inherited from a person's parents. The most common type is known as sickle cell anaemia. It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. This leads to a rigid, sickle-like shape under certain circumstances. Problems in sickle cell disease typically begin around 5 …

Why are there different blood types? | Ask Dr. Universe ...

Type O blood can be transferred to pretty much anyone who needs it. Fyfe-Johnson explained that the blood types we have today evolved a very long time ago. Type A is the most ancient blood type and has been found in hominids – or pre-humans. Scientists can use DNA from some blood cells found in fossils to help figure this out.

Understanding Genetics

By the time we are born, we have on average 100 or so new mutations. This is important to know because the differences between A, B, and O blood types are actually very small. This makes it more likely that a small change can cause an O mom to make an A egg (or an O dad to make an A sperm). What changes are we talking about?

Blood Types of Abductees: What Could They Indicate?

An argument has been advanced that Rh O- blood type is not a mutation and is unrelated to the other Rh antigen groups. This hypothesis suggests that the Rh negative variant of the Rh O+ blood line was not the result of natural mutation. I understand this view to be; the rarity of the Rh O- blood type coupled with its reputed status as a ...

Chapter 7: Genetics Lesson 4: Mutations

A point mutation is a change in a single nucleotide in DNA. This type of mutation is usually less serious than a chromosomal alteration. An example of a point mutation is a mutation that changes the codon UUU to the codon UCU. Point mutations can be silent, missense, or nonsense mutations, as shown in Table 7.5. The effects of point mutations ...

TIL your semen blood type can be different than the blood ...

A person with blood type 0 has the 00 genotype. Now, since sperm is haploid, it has either one or the other chromosome and it's allele for the gene. When you have blood type A or B, you might have the A0 or B0 genotype, so that your sperm cells can either have A or 0 as genotypes, and thus represent the A or 0 blood type. However, since blood ...

Gene Mutation: Definition, Causes, Types, Examples | Sciencing

Such mutations often result in different amino acids being added to the protein being synthesized. An example is beta thalassemia, a blood disorder caused by mutations to the HBB gene. Diseases like cystic fibrosis involve gene mutation deletion – when nucleotides, amino acids, base pairs or whole genes are removed.
