Hi can an O and an A parent have an O child? After watching dr d do a talk on you tube I thought I understood him say that an AO couple could only have an A child as the A dominates

Yes, A+O can produce O if the A carries a recessive O gene (AO). If the parent is (AA) then an O child 'would not happen'.

Here is a chart with all the blood types - father's blood type across the top and mother's blood type down the side.  It gives you all the possible combinations.

Of interest is that an A and a B can have children of all 4 blood types.  That makes menu planning for the family REALLY FUN!!!!

My mom is O- and dad is A+; 2 definite type O siblings, 2 definite type A's(including myself), and one sibling I"m unsure of blood type but willing to bet is a type A.

So, according to the punnet square analysis, my dad would have had to have a recessive O gene. But I'm also willing to bet that my mom's mom was a type A based upon her medical history and personality. Perhaps that explains the fairly even mix of O's and A's in my immediate family. Very interesting topic.

My mom was an A & my dad an O.  Both my sis & I are Os.  So, when I found out my mom was an A, I knew her recessive was O.  From what I have learned about BTD & the diet we had as children, I am certainly glad we are Os!!

I was also wondering what my parents may be, so thanks for those links!

I wonder whether parents with recessive's e.g. your mom as A with recessive O - would be affected by the O blood type?  The reason I ask is, I 'think' both my parents may also have been O's due to their constitutions and how I know that certain foods affect(ed) them, but if not, and one was an O and the other A or B e.g. then could the affect be from the recessive O, or are they more likely to be both O's? if that makes sense !

Lisa,
My Mom is an A from an A mom and an O dad.
I am an A from an A mom and an O dad.
My DH is an O from an A mom and an O dad. We have an O son!

When the A's carry an O and mate with an O they can have either A or O.

my Mom was an O and my Dad an A.

I am O and my brother is A.

My brother married a B and they have O daughters - from this I know that my sil is B&O (not Bang & Olufsen!    ). They have an AB son as well. I noted his markedly unique character since he was a toddler.

If I'm an O and my husband is an O... doesn't that mean we will have O children? I joked with him saying "we know what happened if I pop out a non-O kid"... LoL bad humor, I know.


Husband = O which = easier meal planning!!!

That's right.  If you are both Os you will have O children because O is recessive.

Cat 2:  I think you are asking if the recessive affects the diet.  So far, the BTD experts say no - at least the last I heard.

Dr James D'Adamo, late father of Dr Peter D'Adamo, did publish a book where the recessive alleles were taken into account. I'm not as familiar with his work as my local library didn't have the book available to borrow. So, if you heard anything about an AO having a different diet from an AA, that's where it came from. It's not something Dr Peter D'Adamo considers in BTD, GTD, or even in the personalized SWAMI.

Everybody has two blood type alleles, and one from each parent gets passed along to each child.

Somebody who's blood type A could either be AA or AO. That means that some As can only pass along an A allele, while some can pass along either an A or an O allele.

Somebody who's blood type B could either be BB or BO. That means that some Bs can only pass along a B allele, while some could pass along either a B or an O.

Somebody who's AB has one A and one B allele. They pass along either an A or a B to each child.

Os are all OO. We only have Os to pass along to our children.

My daughter are Os, so they got one O from me and one O from their type B father (who we know is  BO, not a BB, because of his daughters.) Meanwhile, my type B son must be "BO" and not "BB" because we know he had to have gotten an O from me.

My mom is an O and my father was a B. I know my brother must be either an O or a B, but I have no clue what blood type his wife is, and my niece and nephew could be any of the 4 blood types.
