(Altair) Was RH negative blood originally the result of some genetic manipulations?
A: Yes
(Altair) If so, for what purpose?
A: Those most connected to off-world bloodlines.
Q: (L) So was it genetically manipulated off-world in an older time and place? Is that what you're suggesting?
A: Yes
Q: (L) And it's more closely connected. Are these bloodlines negative bloodlines?
A: Some but not the way promoted by the ignorant.
Q: (L) You mean all those people who say if you've got RH negative, you're reptilian. Is that it?
A: Yes
Q: (L) Well, my mother had RH negative blood. I don't think I'm a reptile. I didn't get it though. Okay, background to the next question:
What are the odds that this genetic manipulation is a continuing interference?
A personal example where an A+ mother has two daughters to different fathers and both daughters are 0- blood type. I asked grok what the odds were of that and while it's not impossible, the odds are very low. I asked the question three times since grok gave an approximate answer and the highest of the three answers was 1.64%
Grok's calculation below:
I asked if both O and Rh- were recessive to clarify my understanding of the above:To determine the odds of a woman with A+ blood having two daughters with O- blood with different fathers, we need to break this down into the genetics of ABO blood types and Rh factors, then calculate the probabilities step by step.
Step 1: ABO Blood Type (A to O)
Step 2: Rh Factor (+ to -)
- A+ blood type: The woman has the phenotype A and is Rh-positive. For ABO, her possible genotypes are AA or AO (since A is dominant over O).
- O- blood type: Each daughter has the phenotype O and is Rh-negative. For ABO, the genotype must be OO (since O is recessive).
- For a child to have O blood, they must inherit an O allele from both parents. Since the woman has A blood, she must carry the O allele (genotype AO). If she were AA, she couldn’t have an O child, so we assume she is AO.
- Father’s contribution: Each daughter’s father must contribute an O allele. This means each father must have at least one O allele (genotypes OO, AO, or BO).
- Population frequencies (approximate, based on general data):
- O allele frequency: ~0.63 (common in many populations).
- A allele: ~0.33.
- B allele: ~0.04.
- Probability a random father has at least one O allele:
- OO: 0.63 × 0.63 = 0.3969.
- AO: 0.33 × 0.63 = 0.2079 (x2 for OA order = 0.4158 total).
- BO: 0.04 × 0.63 = 0.0252 (x2 = 0.0504 total).
- Total = 0.3969 + 0.4158 + 0.0504 = ~0.863 (86.3%).
- For an AO mother and a father with at least one O allele to produce an OO child:
- Mother (AO) gives O: 50% (0.5).
- Father gives O: If he’s OO (100%), AO (50%), or BO (50%), weighted by their prevalence among O-carrying fathers:
- P(OO) = 0.3969 / 0.863 = 0.46 → 100% O.
- P(AO) = 0.4158 / 0.863 = 0.48 → 50% O.
- P(BO) = 0.0504 / 0.863 = 0.06 → 50% O.
- Weighted avg = (0.46 × 1) + (0.48 × 0.5) + (0.06 × 0.5) = 0.46 + 0.24 + 0.03 = 0.73.
- Child is OO: 0.5 × 0.73 = 0.365 (36.5%).
Step 3: Combined Probability per Daughter
- A+: The woman is Rh-positive (genotype RR or Rr).
- O-: Each daughter is Rh-negative (rr).
- For an Rh-positive mother to have an Rh-negative child, she must be heterozygous (Rr), as RR would only produce Rh-positive kids (Rr or RR) with any father.
- Population frequency (approximate):
- R (positive) allele: ~0.6.
- r (negative) allele: ~0.4.
- If mother is Rr (given she has A+ and an r child):
- She passes r: 50% (0.5).
- Father must pass r (genotype rr or Rr):
- rr (O-): 0.4 × 0.4 = 0.16.
- Rr (O+): 2 × 0.6 × 0.4 = 0.48.
- Among O blood type fathers (OO), P(r) = 0.4.
- P(father is rr) = 0.16 / 0.3969 = ~0.403 (since we’re restricting to OO fathers for simplicity).
- P(father gives r) = (0.403 × 1) + (0.597 × 0.5) = 0.403 + 0.2985 = 0.7015.
- Child is rr: 0.5 × 0.7015 = 0.35075 (35.1%).
Step 4: Two Daughters, Different Fathers
- ABO (O) and Rh (-) together: 0.365 × 0.35075 = ~0.128 (12.8%).
Final Considerations
- Each daughter’s blood type is an independent event with different fathers.
- Both daughters O-: 0.128 × 0.128 = 0.016384 (1.6384%).
Final Answer: The odds are approximately 1.64% (or about 1 in 61).
- The woman must be AO Rr (plausible, as ~50% of A+ people are AO and ~33% of Rh+ are Rr).
- Exact allele frequencies vary by population, but these are reasonable averages.
Yes, you’re absolutely right! Both the O blood type in the ABO system and the Rh-negative (rh-) trait in the Rh system are recessive. Let me explain why:
ABO Blood Type: O is Recessive
Rh Factor: Rh- is Recessive
- In the ABO blood group system, there are three main alleles: A, B, and O.
- A and B are codominant, meaning if you inherit an A and a B, you’ll have AB blood type.
- O is recessive because it only expresses itself when paired with another O allele. If you inherit an A or B allele alongside an O, the A or B will dominate, resulting in A or B blood type, respectively.
- So, for someone to have O blood type, their genotype must be OO. If they had AO or BO, the A or B would mask the O, making them A or B.
Summary
- In the Rh system, there are two main alleles: R (Rh-positive) and r (Rh-negative).
- R is dominant, and r is recessive.
- If you inherit at least one R allele (genotypes RR or Rr), you’ll be Rh-positive because the presence of the R allele produces the Rh antigen on red blood cells.
- To be Rh-negative, you must inherit two r alleles (genotype rr), as the r allele doesn’t produce the antigen, and it’s only expressed when there’s no dominant R to override it.
- O is recessive to A and B in the ABO system.
- Rh- (r) is recessive to Rh+ (R) in the Rh system.
- For a child to be O- (OO rr), they need to inherit the recessive O and r alleles from both parents, which is why the mother and father must each carry these recessive traits (e.g., mother AO Rr, father OO rr)
For general interest sake, I asked what the population density of each Rh- blood type was - grok corrected my question

When you ask about "population densities" for A-, B-, AB-, and O- blood types, I assume you mean the percentage or frequency of these blood types in the general population, as "density" typically implies a measure of distribution across a population. Since these are the Rh-negative blood types within the ABO system, I’ll provide their approximate frequencies based on global averages and some regional variations, using widely accepted data.
Blood Type Frequencies (Rh-Negative)
The prevalence of blood types varies by region and ethnicity, but here are rough global estimates for the Rh-negative blood types you asked about, based on data from blood donation organizations and genetic studies:
Key Notes
- A- (A negative):
- Global estimate: Around 6-7% of the world population.
- Details: More common in Europe (e.g., ~7-8% in the U.S., higher in parts of Scandinavia). Less frequent in Asia and Africa, where Rh-negative types are rarer overall.
- B- (B negative):
- Global estimate: Around 1-2% of the world population.
- Details: Relatively rare globally. Higher in parts of South Asia and the Middle East (e.g., India has slightly higher B prevalence), but the Rh-negative factor keeps it low.
- AB- (AB negative):
- Global estimate: Around 0.5-1% of the world population.
- Details: Yes, AB- is indeed "a thing"! It’s the rarest of the eight main ABO/Rh blood types. It’s slightly more common in Caucasian populations (e.g., ~1% in the U.S.) but extremely rare in Asian and African populations.
- O- (O negative):
- Global estimate: Around 3-7% of the world population.
- Details: Known as the universal donor, O- is more common in Western Europe (e.g., ~6-7% in the U.S., higher in some Celtic populations) and less common in East Asia (e.g., <1% in Japan). Globally, it averages around 3-4% when weighted by population size.
Final Answer
- Rh-negative rarity: Only about 15% of the global population is Rh-negative (lacking the RhD antigen), with the majority being Rh-positive. This makes A-, B-, AB-, and O- less common than their Rh-positive counterparts (A+, B+, AB+, O+).
- Regional variation: These percentages shift significantly by region. For example:
- In the U.S., O- is ~7%, A- ~6%, B- ~2%, AB- ~0.6%.
- In East Asia, Rh-negative types drop below 1% due to a high prevalence of Rh-positive genes.
- Among some indigenous groups (e.g., Native Americans), Rh-negative was historically almost nonexistent before European contact.
- Data source: These figures align with estimates from organizations like the American Red Cross, Stanford Blood Center, and global health studies, adjusted for a world average.
Here’s a concise summary of the approximate global population frequencies:
These are rough averages and can vary depending on the specific population you’re looking at—let me know if you’d like breakdowns for a particular country or group!
- A-: ~6-7%
- B-: ~1-2%
- AB-: ~0.5-1%
- O-: ~3-7%
(ScioAgapeOmnis) Yes. The original actual picture is more like wavelengths. It’s just like green and red blotches and stuff. And personally, I can't make out how they got these details in the rendering because looking at it, it just looks, there's like this something that resonates under the pyramid, but it's like a big blob. You can't really make out the details. So I don't know how they said, "Oh, it's eight columns. They have a spiral around each column". That part of it was confusing to me.
I sometimes see video shorts where people and their vehicles have gone missing and a team of men scan waterways and other bodies of water on suspected routes they could have travelled in their cars. They will be sitting in a boat on a waterway showing their scan screen and it looks just as you describe. The men will be saying 'oh look, there's a car' and I can't see anything that looks like a car on the scan screen. I guess these instruments need some sort of training to be able to interpret the red, green and orange blotches.
Thank you all for sharing the session
