Genetic ??

[nicnacs_4u]

A question please that someone who knows about "genetics"might be able to help me..

2 sisters with the same parents would they have the same blood group?tia

[downeyas]

yes!

[polksaladallie]

No !

Meaning could have, but may not have.

[cherry*135]

No.

From the net:
The only sure thing is that if both parents are Type O, all their children will be Type O. For the other types, there are other possibilities.

[lyne-flyn]

No....not necessarily...my son is O+ and my daughter in law is A- ...one grandson is O and the other is A

Some good blood type charts here.

I have studied Genetics. The short answer is not necessarily 🙂

If this is a real life question, it's a good idea for everyone to know their bloodtype. Next time at a GP ask for it to be tested.

[polksaladallie]

Costs too much.

Good to know if you need a transfusion though. O-ve can be given to everyone but still good to know what you have.

I didn't know that O- could be given to everyone.  I can't remembeer exactly what type my dad had but it was a much less common one than O+.  When he was living in Perth the blood bank used to send a taxi for him for his regular donations.

I am a boring O+ but I guess that means I am lucky if I need blood.
