if i hadn’t found this video I would be up all night trying to understand the rhesus factor. Thanks so much, I have a major exam tomorrow and this helped ALOT.
The most famous celebrity blood types are Rh negative, such as Jack Nicholson, Clint Eastwood, John Lennon, Steve McQueen, Queen Elizabeth II, Leonardo DiCaprio, Paul McCartney, Johnny Depp, Kurt Kobain, and Elvis Presley.
Thank you for this easy explanation, both of my parents were O- and my Daughter is also O- but her Father was A+ so apparently one of his parents was Rhésus Negative and my guess would be his father who also had blue eyes, his Mother had brown eyes. My Daughter has green eyes and mine are blue and green (heterochromic) like my Paternal Grandfather's. My Daughter got not only her blood type from me but also her eye color, her Father had brown eyes.
brown eyes are dominant over blue eyes, and green eyes. But green is dominant over blue. My dad had blue eyes and my mom brown, but she must have carried a recessive for blue because ALL of my siblings have blue eyes. And even though my eyes are dark, I obviously got my dads genes for blue eyes and passed that to my daughter, who has green eyes like HER dad. someone can have A+ blood, both dominant traits, but carry recessive O negative, sounds like the recessive O and recessive negative was passed to your child in the sperm that fertilized your egg. Children get their traits from BOTH parents, not only one as he demonstrated here. Its' about whether something is dominant or recessive
Dear docter, or readers whom can help me out! I have a question, i have been told that my blood type is O positive but i have RH negative. Is this possible? Because i am pregnant and this is very important! I jave beenntold by blood bank that i can give blood to everyone but not receive from anyone. So the nurse madee confused about my blood type!!!!!!!
You are just O Neg. You can’t be both. I am also O Neg and yes every blood type can receive our blood, but we can only receive O Neg. We are around seven percent of the world population. In an emergency, a hospital will give a trauma patient O Neg if they don’t have time to figure out blood type. Blood banks message me every other day usually. With you being a RH negative and pregnant, they will give you the shot, (I forget the name) that will help with incompatibilities between you and your child’s blood type. In case there is contact during birth. I believe if it’s your first pregnancy, you don’t need it, but will on pregnancies after that.
Daim Mehmood Excellent point, but they do when they are forming from stem cells in the red bone marrow. They lose the nucleus as they mature, just prior to release into the systemic circulation. In fact nuclear fragments are still visible for the first few days, these young red cells are called reticulocytes.
Am rh D negative A but my mum is O positive I have no idea what my dad is. I have 2 children 1st child was bad he or me could of died because our blood was mixing so had to get an emergency C section he needed two blood transfusions an my 2nd child got an emergency C section to dnt no why because she has same blood type as me and she needed one transfusion. My partner has A positive blood. So am a bit confused as hospital said I should not have this blood for me to have this someone blood would have to mix with mine or blood transfusion and none has happened, it's a weird one
If your type is A negative, but mom is O positive, your mom would have had to be a carrier for negative blood, that's how you got negative. And you got your other negative from your dad, who had either blood type A or AB but the sperm that fertilized the egg that made you carried A and rh negative. Because your husband is A+ , and positive dominates negative, even though all your eggs will carry negative, his sperm will either always carry positive, or sometimes if he's a carrier for negative like the example given on the chalkboard here. If the baby was positive, a negative mothers body forms antibodies against it and it often results in miscarriages, or sometimes transfusions. Not sure when you had babies. but in 1968 they came out with a Rhogam vaccine and it's given to a negative mother who might have a positive fetus, to help her carry the baby full term and prevent her body from attacking future positive babies. New injections are given with each pregnancy, during and after
Thank you for a wonderful explanation. I'm O Rh negative with phenotype ccddee. My husband is A Rh positive with phenotype CcDee , kk. I wonder is there one letter "d" missing in his phenotype? Since I hope to get a chance to have one Rh negative child...
John, I really like your videos. I would like to know what the antigens mean. Heart attack risk, disease risk and so on. I am O- and I am constantly being reminded that I need to give blood. I know that my blood is universal for the most part. I am CMV neg also so I am on their radar. What do all of these stickers mean during this Covid Pandemic?
So 15% of the population is RH- and being that also r O you could be a donor since u could donate 2 all 3 types as long as their negative, it's essentially the top dog of the negatives. They said O was not getting affected with Covid as much
If 15% of the population is Rh negative, you can't say the women in the UK are 15% of the population. Wouldn't about half of the negative population be naturally Male? So the women would be only about 7% of the total UK population. And the child bearing portion would be even less, some are too young, too old, have no desire to have children or fertility problems. Unless you are saying that men in the UK cannot have negative blood.
sir, u mean that this is dominant inheritance pattern but according to Edward F. Goljan the Rh-system follows a co-dominant pattern..so who z correct??

Dr John is the most intelligent man on TH-cam!! Thank you so much, this really helped me!
You are such a brilliant teacher John! Thansk you!
We are the original blood type. 0 negative
Why does christ have AB neg?
very educational doctor, thank you...
Brilliant sir
Your teaching methodology is exactly same to our teacher
Excellent description 👍

My mom had six kids, with zero miscarriages. I am RH negative. I’m trying to determine if the likelihood is that my dad was rh neg?
Thank you John

So does the Rhesus recessive gene arise from a mutation in the dominant gene, that makes the former recessive in nature?
What is there to mutate? If someone is lacking the D antigen (they are negative). If they have the D antigen they are positive
@@recoveringsoul755 my question was on the origin of the recessive gene not on basic genetics, which is quite evident
@@aggarwalkaoor9002 have you seen Robert Sepher's work?
@@recoveringsoul755 no. Will have a look. Thanks
what chromosome ???? dear sir please explain :( RBCs have no nucleus

Dr. John Campbell oh yes exactly the blasts cells does have nucleus :D thanks a bunch
What if my wife is Blood type O and she's pregnant with my child and her results for rh factor was "Weak D"? Is that concering?
Exactly what I have been looking for. Thank alot

Does the Rh factor obay multiple allels or polygens

Where are antibodies produced from
Plasma cells are the ones which produces all antibodies(IgG,IgA,IgM,IgE and IgD)
i love ur explanation ^ ^ > thx
my mom is A and my Dad is B but why am I an Rh type?
A and B groups are inherited separately from the Rh factor
sir does it mean I may have an AB blood with an Rh factor? or is it different? 😭
sorry I'm just confused.
Yes, you could be A, B, O or AB from your parents. The Rh factor is inherited separately, so you may be positive or negative.
You need to watch some of the genetics videos to understand the mechanisms, I have uploaded a genetics series under campbellteaching.
Thank you for the explanation
Thank you
I have studied that the Rh factor depends on three pairs of genes isn't
Six alells
We dont mutate. Im 0 negative. Look at king tut and ancient redhair mummies.
Yes, I remember seeing a mummy in the British museum with red hair, guess the gene was around in ancient Egypt.
@@Campbellteaching do you know something about purple eyes and rh neg blood ?

31th time donoring my blood... Today i know what r¹r² on my blood donor book....
The nurse said to me you have rare blood..
I said what 😳
No it does not. If we have a baby with our own race with 0 negative its fine. Or get antirejection shots qnd bqby is fine.
