How many are the incorrect statements from the followings:
a) Lower the taxa, more are the characteristics that the members within the taxon share
b) Higher the taxonomic category, greater is the difficulty of determing the relationships to other taxa at the same level.
c) In lower taxa as the problems of classification becomes more complex.
d) As we go higher from species to kingdom, the number of common characters increases.

Explanation

To determine how many statements are incorrect from the provided options, we will analyze each statement one by one.

### Step 1: Analyze Statement A
**Statement A:** "Lower the taxa, more are the characteristics that the members within the taxon share."
- This statement is **true**. In lower taxonomic categories (like species), organisms share more characteristics because they are more closely related.

### Step 2: Analyze Statement B
**Statement B:** "Higher the taxonomic category, greater is the difficulty of determining the relationships to other taxa at the same level."
- This statement is also **true**. As we move to higher taxonomic categories (like kingdom), it becomes more challenging to determine relationships because the organisms are more distantly related.

### Step 3: Analyze Statement C
**Statement C:** "In lower taxa as the problems of classification becomes more complex."
- This statement is **true**. In lower taxa, while there are many shared characteristics, distinguishing between closely related species can be complex due to subtle differences.

### Step 4: Analyze Statement D
**Statement D:** "As we go higher from species to kingdom, the number of common characters increases."
- This statement is **false**. As we move from species to kingdom, the number of common characteristics actually **decreases** because organisms at the kingdom level are more distantly related.

### Conclusion
After analyzing all four statements:
- Statement A: True
- Statement B: True
- Statement C: True
- Statement D: False

Thus, there is **1 incorrect statement** (Statement D).

### Final Answer
**There is 1 incorrect statement.**
