Based on prior knowledge, the feature "Sex" may not have a direct relationship with the task of determining whether the coronary angiography of a patient shows heart disease or not. Heart disease does not have a specific association with either gender, as it can affect both males and females.

Nevertheless, we can still generate a dictionary based on the available information. Since there is no specific relationship between the feature "Sex" and the target variable, we can include all possible values of the feature in both target classes.

The dictionary can be generated as follows:

```json
{
	"no": ["M", "F"],
	"yes": ["M", "F"]
}
```

Please note that both target classes include all possible values of the "Sex" feature, as there is no specific relationship to consider.
