Anonymous users2024-02-07It's not that the odds are small, it's impossible to have three kinds of children: A, B, and AB if the parents are A, B, and B The parents will also have type O blood, and if one of them is AB, the probability of the child's blood type O is 0
Both parents have blood type O+O
The child's blood type may be O
The blood type of the child cannot be A, AB, or B
Blood type O+A of both parents
The child may have blood type A and O
It is impossible for a child to have AB or B blood type
Both parents have blood type O+B
Children may have blood type B or O
It is impossible for a child to have a blood type A or AB
Parental blood type O+AB

Anonymous users2024-02-06Is it possible? I also want to know, probably very unlikely.

Anonymous users2024-02-05Of course not! It could be A or B or AB, and there is no other blood type!

Anonymous users2024-02-04Blood type O is not possible unless one person is O.

Problem description: There must be a basis!
Analysis: If the parent is type O or AB, the offspring is type A or B.
In general, blood type is constant throughout life. Blood type is like a natural "identity card" given by parents to their children that cannot be altered.
A, B, O blood types are inherited according to the law of Mendelian genetics, A, B, O, AB four blood types from the genetic point of view, A type has AA and AO two genes, B type is BB and BO, O type and AB type each is one, that is, OO and AB. When both parents are type A and both genes are AA, the child can only be type A. If both parents have Ao genes, the blood type of their children can be A and O.
If one parent is a parent with a gene AA and the other parent is a type A parent with AO, the child's blood type is either a gene AA or a parent with AO. The occasion of Type B is exactly the same. For parents with type O and AB, the child has a genetic identity of AO or BO, i.e. it can only be a blood type A or B.
When both parents are type O, and of course the children are also type O, and when both parents are blood type AB, there are three possible blood types of children: type A with the gene AA, type B with BB, and type AB.
Both parents have blood type O+O
The child's blood type may be O
The blood type of the child cannot be A, AB, or B
Blood type O+A of both parents

Anonymous users2024-02-01Answer]: iaibio
is a complex allele, where IAIB pairs IO
It is dominantly band-resistant, IA
and IB are co-dominance. Type AB is IA
IB produces two kinds of gametes
The IBO type is IO
IO produces a gamete IO
Both children have either IAIO or IB genotype
IO is a type A or B, but not AB type first town.

Anonymous users2024-01-31Principles of blood group testing.
Blood type is determined by the combination of three genetic factors such as A, B, and O, and most of them can be judged according to the blood type of the parents.
The genetic law of blood group is:
a＋a→a、o；
a＋b→a、b、o、ab；
a＋o →a、o；
a＋ab→a、b、ab；
b＋b→b、o；
b＋o→b、o；
b＋ab→b、a、ab；
o＋o→o；
o＋ab →a、b；
ab＋ab→ab、ab。
Therefore, according to the above blood group inheritance law, if the husband and wife have blood types "A" and "B", the baby's blood type will have "O" or "AB" in addition to "A" or "B".
