To determine the possible genotypes related to blood group in the context of a man and woman having a girl child, we need to first recognize the blood group inheritance.

### 1. ### Break Down the Problem
- Identify the possible blood group alleles: $ I^A $, $ I^B $, $ i $
- Recognize the phenotypes (blood types) that correspond to these alleles:
- $ I^A I^A $ or $ I^A i $ leads to blood group A
- $ I^B I^B $ or $ I^B i $ leads to blood group B
- $ I^A I^B $ leads to blood group AB
- $ ii $ leads to blood group O

### 2. ### Relevant Concepts
- Blood group inheritance follows Mendelian genetics, where A and B are co-dominant and i is recessive.

### 3. ### Analysis and Detail
Identifying the possible blood groups of the parents that can yield a girl child requires examining potential combinations.

Given the options:
1. **IBo, IBIB**
- Possible blood types: B (IBo) and B (IBIB)
- Possible genotypes for a child: IBi, IBi, or ii (impossible for AB or A).

2. **IBo, IoIo**
- Possible blood types: B (IBo) and O (IoIo)
- Possible genotypes for a child: IBi, ii (possible).

3. **Only IBIB**
- Possible blood types: B (IBIB)
- Possible genotype for a child: IBIB (all children will be type B).

4. **Only IoIo**
- Possible blood types: O (IoIo)
- Possible genotype for a child: ii (all children will be type O).

### 4. ### Verify and Summarize
Analyzing the combinations:
- For **IBo, IBIB**, the child can be B or O (impossible for A or AB).
- For **IBo, IoIo**, the child could be B or O.
- **Only IBIB** will yield only type B children.
- **Only IoIo** will yield only type O children.

### Final Answer
The possible genotypes in context to blood group if the man and woman have a girl child can include:
- **IBo, IoIo** (yields either B or O children)
- **IBo, IBIB** (yields B only)
- **Only IBIB** (yields B only)
- **Only IoIo** (yields O only)

Thus, the actual combinations depend on the parents' actual genotypes. If the child is type AB, neither option applies.
