I try explain (with my poor English) cat´s blood group and combinations.
There are knowen 3 blood group of cats: A, AB a B. Type A is A=AA (Aa) or A=AB (Ab), where A is dominant. Type AB is rare and we still don´t know many informations about its.


Genetica of blood group:
explanatory text for describing combinations:
mother female + father male = offsprings kittens
Aa = blood group A (clear A) with two alleles A
Ab = blood group which is carrier for blood group B (one allela is A and second allela is B)
B = blood group B (always both allelas are BB)



Aa + Aa = Aa (the best combination + both parents are clear Aa and all kittens are clear Aa )

Aa + Ab = Aa or/and Ab (all kittens will be have blood group A, but some from them will be Ab = carriers blood group B from their father)

Aa + B = Ab (all kittens will be have blood group A and togheter all kittens will be carrier blood group B from their father)

Ab + Aa = Aa or/and Ab (all kittens will be have blood group A, but some from them will clear Aa and/or some of them will be Ab = carriers blood group B from their mother)

Ab + Ab = Aa or Ab or/and B (from this combination is possible to havae in one litter all blood group - Aa, Ab and/or B )

Ab + B = Ab or/and B (if mother is Ab and father B, all kittens from this pair will be have blood group Ab and/or B)

B + Aa = Ab !!! (mother is blood group B and father Aa - all kittens must to be separate from their mother for 1-3 days!)

B + Ab = Ab !!! or/and B (mother is blood group B and father is blood group Ab - some kittens from the litter must to be separate from their mum for 1-3 days, we need to buy products for fast blood group test, which can do during delivery)

B + B = B (both parents are blood group B,there is no problem for their offsprings but we have to give a notice about it to new breeder of our kitten from such parents).
