Answer:
They could have all four type phenotype that are A, B, AB, and O
Explanation:
If the man has A blood group and the woman has B blood group then the genotype of man can be IAIA or IAi and the genotype of woman can be IBIB or IBi. 
                IA      i
        IB   IAIB   IBi
        i     IAi       ii
So if the genotype of the parents are IAi and IBi then out of four offspring one could have AB blood group, second could have B blood group, third could have A blood group and fourth could have O blood group as shown in the cross above.

Answer:
Binary fission.
Explanation:
Reproduction may be defined as the process of production of the offspring to produce more of its own kind. Two main types of reproduction are sexual reproduction and asexual reproduction.
Asexual reproduction involves only one one parents and produce the offspring that has same genetic material. Binary fission is the main type of the cell division used by unicellular organism. The cell divide into two daughter cells with the same genetic constituents.
Thus, the answer is binary fission.
