my parents have both taken the secretor test and have come out as secretors. does anyone know whether this means i'm also a secretor? i thought i was anyhow just based on the recommended foods, etc.--just trying to figure out if it's worth springing for the tst. it probably is

Since the nonnie gene is recessive you could still be nonnie. Kind of like blue eyes from brown eyed parents. It happens.

Nonsecretor is a recessive trait.

Therefore if both parents are secretors, a child could be a secretor or a nonsecretor.

If both parents were nonsecretors than the child will be a nonsecretor.

You'll have to test to find out your secretor status.  I'm a non-secretor born of two secretor parents.  

In the below Punnett Square, similar to a multiplication table, I show the possible outcomes from a pairing of two Secretor parents.

A gene is made up of two alleles.  Offspring receive one allele from each parent.  

Se represents the secretor allele.

se represents the non-secretor allele.


In the followig example, I assume that each parent has a recessive non-secretor (se) allele.  They are both secretors (Se) therefore they also each have a secretor (Se) allele.



The four outcomes include:

1) Se Se - two Se alleles combine to make one a Secretor

2) Se se - Se and se alleles combine to make one a Secretor

3) Se se - Se and se alleles combine to make one a Secretor

4) se se - two se alleles combine to make one a Non-secretor

In the above example, each child of this paring would result in a 3/4 chance of being a secretor and a 1/4 chance of being a non-secretor.

Stay tuned, for the example where only one parent has a recessive non-secretor allele and the example where both parents have all secretor alleles.

Stay tuned - one more possibility for the parents!

Final possibility for two secretor parents:

In the below Punnett Square, similar to a multiplication table, I show the possible outcomes from a pairing of two Secretor parents.

A gene is made up of two alleles.  Offspring receive one allele from each parent.  

Se represents the secretor allele.

se represents the non-secretor allele.


In the followig example, I assume that both parent have two dominant Secretor (Se) alleles.  They are both secretors (Se).  The mother has two Secretor (Se) alleles and the father has two Secretor (Se) alleles.



The four outcomes include:

1) Se Se - two Se alleles combine to make one a Secretor

2) Se Se - two Se alleles combine to make one a Secretor

3) Se Se -  two Se alleles combine to make one a Secretor

4) Se Se - two Se alleles combine to make one a Secretor

In the above example, each child of this paring would result in a Secretor.

and I was persuated that it might be that if one of the parents is a so called *silent* nonnie, he/she only carries the gen.... the offsprings might /will be nonies... ok in my case I am nearly sure that all members of that blo...families were nonnies...  all too weird for not being...haaa...anything else....

So it follows that if both parents are non-secretors, all the kids will be non-secretors as well?

Being a little lazy, but does anyone know what the actual gene marker is for this? Or location, etc.? I don't know the terminology yet.

I'm guessing both my parents are secretors and carry the nonnie gene that I so luckily inherited.  My parents and both brothers are as strong as oxen and I seem to be a bit more fragile.  My parents are 89 years old with relatively minor health issues and have consumed wheat and coffee their whole lives (dad is O, mom doesn't know her blood type).  I hope my nonnie-ness doesn't cancel out all the good things I must have inherited from them!
