Is it possible to enjoy an entirely different blood group to both parents?
My Dad is A-
My Mum is B-
But I am 34 years old now and recently found out I'm O-
Is this possible?
Answers:
Yes.
The genotype for A type blood is AA or AO
and the genotype for B blood is BB or BO
The genotype for O is OO
Because you are O, your parents genotypes are AO and BO
Yes it is.
A pair have groups A & B can produce children with group A,B,AB or O. It's simple Mendalian genetics, but I don't think you would want me to turn into details :)
So don't worry. They ARE your parents!
(Now if you were O+, THEN we would have a problem ;) )
That is enormously possible. Like the one said above, Blood type A can have an allele of IA IA (homozygous dominant) or IA i (heterozygous), B can have IB IB (h.d.) or IB i (heterozygous), and O can only enjoy i i(homozygous recessive).
In your case, the only way of getting a blood type of O is when your parents own both heterozygous alleles which are IA i and IB i. Through Mendelian genetics, there is a 25% chance of getting an AB, A, B and O blood type, respectively.
Bottom smudge, yes it is possible. Source(s): I just learned it from my Biology class. : )
It's comparatively possible. You Mum has an A allele and an O allele, and your Dad has a B allele and an O allele, so you ended up next to the two O alleles.
