Question more or less blood types?
Answer:
No - in the given scenerio - Type A- x O+ - it is impractical for the offspring to be type AB -- impracticable at all...
To simply we will not even traffic with the Rh factor... Type A individual are any homozygous (AA) or heterozygous (AO). Type O individual are alway OO. So...
AO X OO = 1/2 AO and 1/2 OO --- or 1/2 type A and 1/2 type O
AA X OO = 100 % AO --- all brood are type A.
A type AB individual needs both the A antigen and the B antigen -- one antigen is adjectives from each parent. B antigen do not of late magically appear in the genome. Antigen are co-dominant alleles (along near the A antigen) -- you can only attain the antigen from mom or dad...
No. Someone was cheating. Scandalous.
It is ALWAYS possible. Please apprehend that the typing you learn surrounded by biology and which often appears on the Internet is extraordinarily simplistic. If you are questioning parentage, consequently get a DNA assessment. People can be recessive for virtually any blood type. I started questioning this when I found out that near are documented cases of people shifting blood type, specifically, the RH factor going from negative to positive.
Both of my parents are O positive. They hold three O negative, 2 O positive and one A positive. There is no cross-examine of parentage.
No it is not. I believe the child would be born with AO blood.
Not unless the litter had the fantastically unlikely mutation that converted one of their ABO alleles into the B edition.
In class, you get qualified a lot of exceedingly simple examples of genetic problems, which can make you meditate that all inheritance is this simple and straightforward.
But it's not true. Very little in inheritance is as simple as the ABO blood types. But I'm pretty sure that the ABO blood types really are that simple.
normally the answer to this is no. blood typing surrounded by biology is taught straight forward because for the most slice it is. nothing have changed in the ending 24 years that i have be doing blood banking concerning blood typing.
here is a rare fact know as an acquired B. it is picked up from the environment and at this point is really not economically understood. An A patients become AB and O patients become B by agreed typing methods. it is not known what cause the acquired B or if it is transient or long term.
so it is possible but outstandingly unlikely.
this most likely cause is the father was a B+.
It is not on because
Generally the A group blood has any AA antigen or OA antigen and similarly the B group blood has BB or OB antigen and the AB group have AB antigen but the O group has OO and so no antigens . when crossing occur , either of the gamete from respectively parent combine to give any the parental or a new blood group.
To be specific to ur press , the mother with A- , may own either AA or OA and the father will enjoy OO . so when the crossing occurs nearby can be two chances
1)'A' from mother and 'O' from father are expressed as 'A' group blood
2)'O' from mother and 'O' from father are expressed as 'B' group blood
I hope i didnt verbs u!
