In the human blood grouping, the four basic blood types are type A, type B, type AB, and type O. The blood proteins A and B are :
(a) simple dominant and recessive traits
(b) incomplete dominant traits
(c) codominant traits
(d) sex-linked traits

Q. Which are some of the dominant and recessive traits in human beings?

Q. Human blood type is determined by codominant alleles. There are three different alleles, known as $I^A$, $I^B$, and i. The $I^A$ and $I^B$ alleles are co-dominant, and the i allele is recessive.
The possible human phenotypes for blood group are type A, type B, type AB, and type O. Type A and B individuals can be either homozygous ($I^A{I}^A$ or $I^B{I}^B$, respectively), or heterozygous ($I^{A}i$ or $I^{B}i$, respectively).
A woman with type A blood and a man with type B blood could potentially have offspring with which of the following blood types?

Q. How do Mendel's experiments show that the
(a) traits may be dominant or recessive,
(b) traits are inherited independently?

Q. In the ABO blood groups inheritance, the A and B alleles are co-dominant, and O is recessive to both the A and B alleles. If a man with type B blood and a woman with type A blood marry, the phenotype of their children could be
