Discussion Overview

This discussion explores the genetic inheritance of the Rh factor in blood types and the possibility of having two hearts or a heart positioned on the right side of the body. It includes theoretical considerations, personal anecdotes, and references to rare medical conditions.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants propose that two positive Rh factor parents cannot have a negative Rh factor offspring, while others argue that it is possible if both parents carry a recessive Rh gene.
  • A participant mentions a family claiming to have a negative Rh factor child from two positive parents, questioning the truth of their statement or the accuracy of blood tests.
  • There is a discussion about the genetic dominance of the Rh factor, with references to Mendelian genetics and the potential for a child to inherit a negative Rh factor from positive parents under certain conditions.
  • Participants discuss the rare condition of dextrocardia, where the heart is located on the right side of the body, and share personal anecdotes related to this condition.
  • One participant humorously shares an incident involving their grandfather's heart placement and the confusion it caused among doctors.
  • There is mention of a condition called pericardial reflection, with a participant unsure of its relation to dextrocardia.

Areas of Agreement / Disagreement

Participants express differing views on the inheritance of the Rh factor, with no consensus reached on whether two positive Rh factor parents can have a negative Rh factor child. The discussion on heart placement includes agreement on the existence of dextrocardia but lacks resolution on the specifics of related conditions.

Contextual Notes

Limitations include the potential for misunderstanding genetic inheritance patterns and the rarity of the conditions discussed, which may not be fully understood by all participants.

can two +ve rhesus parents have a negative rh factor offspring?
Can a person have heart on right and two hearts?
I know it is rare.

I know it is rare.
Positive rhesus can be ++ or +-. Two ++ parents cannot have an offspring with a negative blood group. Both parents need to have a -, as far as I know.

I don't know about 2 hearts, but there is a rare condition called 'dextrocardia' in which the heart is on the right side.
 
But one family was saying that the Rhesus factor of the parents were both positive but their offspring was having negative rh factor. Might be they are not telling truth or the blood test might have given some wrong report?
See this link of Google showing a girl having 2 hearts and a man.

Thanks Raghav. I was actually going post the same question.
My dad himself is Rh -ve and both my grandparents are Rh+ve. I don't know how this is possible.

Siddharth, sadly, your wrong about that, because both the parents need not have Rh-ve for their baby to be a Rh-ve. I'm Rh-ve and my moms Rh+ve. .This I can assure you.

Like I said, the + sign in your blood group isn't the only thing. It can be either ++, +- or --. Your mom must be +-. I'll check it up and let you know.
 
Oh wait!
I just found out.
A baby gets Rh+ve even if one of the acquired genes of the parents is of Rh+ve. so the Rh recessive is trumped by the dominant gene.
There is a possiblity for two Rh+ve parents to have a Rh-ve baby.
This is because, both parents might have a recessive Rh gene, but still expressed as Rh+ve due to the other gene.
so in a rare situation the recessive gene of both the parent's may be passed on to the baby, making him/her Rh-ve
 
Yeah right. The dominant and recessive traits play a part. There are a few laws to it, discovered by Gregor Mendel. If the recessive traits from bothe Rh +ve parents come into the offspring, he will be Rh -ve.

Check this:

So there's about ½ ×¼? chance that such a Rh-ve Baby results from 2 Rh+ve.
is -----------------⤴⤴⤴ right?

It differes in every case. If the two parents are +- and +-, then the child can be-

1) ++ (complete dominance) 2) and 3) +- or -+ ( incomplete dominance) 4) --

Only in case number 4 will the offspring be Rh -ve. So 1/4th chance

Thanks to both of you for explaining more on rh factor, and my heart question is also answered. By the way I was asking that whether a person could have heart on right, just for a worldwide perspective as my grandfather has a heart on right side.
Sharing with you an incident :
The doctors would be confused when they would keep the stethoscope on left of my grandfather and wonder where the heart has gone, because they could not hear any heartbeats.:D

Oh nice and creepyo0).
Is that by any chance the same as pericardial reflection, its really rare.

No, siddharth, I was trying to multiply the probability of both the parents being of +- . How do you do that??

Don't know about pericardial reflection, but
