What are the frequencies of rh negatives in Ethiopia?

Ethiopia is one of the most interesting places when it comes to rh negative blood type distributions, simply because the country in itself is so genetically diverse.
Africans in general have a frequency of 1-3% rh negatives, which is very low, but there are some groups worth mentioning that stand out.

1) The Yorubas
2) The Chad/Cameroon area where tribes high in genetic marker R1b and rh negative blood have migrated to once
3) The Ethiopians whose percentage of rh negatives is almost triple that of the continental average

More than 50% of the Ethiopian genepool matches with Semites, Berbers and Europeans and not Sub-Saharans. An 18% J frequency indicates Sumerian ancestry as well. Ancient Mesopotamians migrating throughout the area once have remained genetically present within the Ethiopians telling us just how ancient civilizations once destroyed saw their members move into the “New World”.

According to recent studies, around 8% of Ethiopians are rh negative.

Neanderthal DNA discovered within the Yoruba people of Africa

According to several studies, Neanderthal DNA exists in all Europeans at a frequency of 1-3% as well as in Asians. Alongside those studies, the claim was made that Neanderthal DNA is absent in Africa.

Recent studies revealed that this is not correct.

Neanderthal genetic signal deep into the homeland. Indeed one of Reich’s analyses, published last month, found Neanderthal traces in Yoruba DNA (Nature, DOI: 10.1038/nature12886).

The Yoruba people have also been singled out as a group with a high percentage of rh negatives.

Up to 30% of Sinai Bedouins found to be Rh Negative

Although the Rh-negative trait is rare in most parts of the world, it occurs in about 15 percent of Caucasians in Europe, Canada, and the United States. The trait’s highest incidence is among the Basques of the Pyrenees (25–35 percent) and the Imazighen (Berbers) of Africa and the Bedouins of the Sinai Peninsula (18–30 percent).

So who are the Bedouins genetically speaking?

You may be surprised.

Studies indicate higher risk of autism amongst children of rh negative mothers

In the past few years, the claim that rh negative women are more likely to have autistic children has come up again and again. But is there truth to this claim or is it merely a myth?
One fairly new study shows that children born before 2001 are much more likely to have rh negative mothers. The potential reason behind it given:

The Anti-D shot contained mercury until that time.

There were significant and comparable increases in maternal Rh-negativity among children with NDs (Clinic: A=24.2%), autism spectrum disorders (Clinic: A=28.3%, B=25.3%), and attention-deficit-disorder/attention-deficit-hyperactivity-disorder (Clinic: A=26.3%) observed at both clinics in comparison to both control groups (Clinic: A=12.1%, B=13.9%) employed. Children with NDs born post-2001 had a maternal Rh-negativity frequency (13.6%) similar to controls.

This study associates TCR exposure with some NDs in children.

So what about children born after 2001?

A study conducted by the University of California in Davis has revealed that MAR antibodies in the mother´s blood are responsible for 25% of autism cases in the United States.

Let´s look at it this way:

Back before there was an Anti-D shot, an rh positive fetus of an rh negative mother would simply die or “vanish” if the mother already had antibodies. Now that after 28 weeks of gastation the shot is being administered, we are dealing with 7 months of potential damage being done. If a fetus survives, then the brain activity can be harmed by those antibodies.
Note: In countries with lower levels of autism, the shot is usually given after the birth of the first rh positive child ensuring antibodies being built up while in the U.S. it is given almost towards the end of the pregnancy.
Could this be why there is an autism epidemie in the States?


The alleged autism epidemy began in the early 70s. 1968 was when the Anti-D shot was approved for administering.

If you are an rh negative woman wanting to get pregnant by an rh positive man, here is my advice:

Visit your doctor before you get pregnant and ask for an antibody screening.

If your child is autistic or has Asperger´s:

Allow your child to show you what he or she has interest in. Forcing a child to do what everyone else is going is never a good thing. Rather than turning everyday life into a chore, allow your kid to follow his or her instinct.
In order to bridge social awkwardness, find other children with similar interest.
That way the move from being interested in something towards having interest in others who share those passions helps build a foundation for a better social life once an adult.


There are many sites and communities out there helping mothers of children with Neurodevelopmental Disorders. Everyday Aspergers is one that I recommend.
Many of the members from that page are also on People with Rhesus Negative Bloodtype, so if you are on Facebook, use our page to exchange ideas with other mothers of autistic children if that is what you are.

Rh Negative frequencies higher than 30% in parts of Scotland

Scotland is a very interesting place when looking for frequencies of rh negative people because of its strong variation of numbers based on locations.
According to “Distribution of the ABO and rhesus (D) blood groups in the north of Scotland” by Elizabeth S Brown, people in the region of Inverness top the list of rh negative people in Scotland with a whopping 30.44%.

What type of diet is ideal for Rh Negative people?

Recently I have spent time reading up on material on food and what would be best for us.
What I have learned more than anything is that in order for us to truly be healthy, we need to relearn basically everything.
I remember as a child never being a fan of potatoes and bread. I liked meat and vegetables.
I was taught I needed to eat my carbs.
So what did I find out?
More than anything I have discovered that what our body tells us to consume is usually the best diet. That means that when you crave something, you should eat it.
But be aware:
If you crave potatoe chips, it is not the actual chips you are craving. It is the artificial flavors. So when you crave paprika chips, maybe preparing a meal containing paprika for dinner would be the right answer.
Your body doesn´t lie to you, but there is a big food industry financially benefitting from misleading your body into believing their product is what you need.
In addition I have learned that diabetics can live without insulin restricting their diet to meat and vegetables only.
Bread for example is not food. It is filler. It also contains unusually high amounts of salt raising your level beyond what is recommended as daily intake in addition to sugar.

no bread

A survey of salt levels was carried out by lobby group Consensus Action on Salt and Health, which is calling for honest labelling and a change in recipes.

The group, which says bread is responsible for a fifth of daily salt intake, surveyed 294 fresh and packaged loaves from supermarkets and in-store bakeries, as well as chain and independent shops.

More than one in four – 28 per cent – contained as much salt, or even more, per slice than the 0.5g in a standard 34.5g packet of Walkers Ready Salted Crisps.

What type of food do you crave and how do you generally feel about your health?

Rather than fill up on potatoes – which have been found to promote weight gain – choose beans for an excellent source of slowly digested carbohydrates. Beans and other legumes such as chickpeas also provide a healthy dose of protein.

The Interview:


1) Lici, thank you very much for taking the time to conduct this interview.
When did you first find out about your blood type, when did you
gain interest in the rh negative blood factor and what keeps you
motivated in terms of upgrading your research?

About 3 years ago , when I had my general blood check-up. Since then, I’ve been interested and gotten motivated .Then the fact that there are alot of Indonesians (local people) with Rh negative blood type.

2) Out of all the things you have learned researching the rh negative
blood factor, which discovery stands out in terms of opening your eyes
the widest?

About pregnancy. Woman who are Rh- and their pregnancy. I have come to find out that people (including doctors) have a preception here that Rh- women will face a general risk when pregnant and at worst that we cannot have a baby.
Almost everyday we get messages via phone, web, our FB group that an Rh- blood donor is needed (not only from Jakarta). Or people just find out that their blood type is RH-. They ask alot of question why they have this type of blood or pregnanct woman with Rh- have a need for a standby donor for their birth giving preparation.

3) What is your most passionate area of interest?

To convince the Indonesian government to explore about Rh Negatives, including introducing a policy for all Indentity cards to have people´s blood types written on them including the Rh factor.

4) What are your plans for the near future?

To create more events , campaign for awareness about the Rhesus negative blood factor. We have to do it now or it will be too late.

5) How has your mission changed since you have first gotten started and what types of goals are you setting for the next year with Rhesus Negatif Indonesia?

Simple mission for this year: Make the public and our government aware of the word #RHESUS.

6) Have you received support from outside sources such us other
organization (like the Red Cross) or government agencies? If not, how
hopeful are you in getting those who should be interested in your
mission to show interest and provide you with assistance and have you
been reaching out to any of them in the past?

Not really a support I think. With the Red Cross we are just doing coordination of Blood Donors. The government? No , we have never gotten any of their support.
