Based on standard pedigree analysis symbols described in the text and Figure 4.13:

1. Sex unspecified is correctly represented by a diamond shape .
2. Affected individuals are represented by solid or shaded symbols .
3. Consanguineous mating (mating between relatives) is represented by a double horizontal line connecting the parents. A single horizontal line represents normal mating . (In many exam questions, this option is paired with a single line symbol, making it the incorrect match).
4. Parents with a male child affected with disease are represented by parents connected by a line, with a vertical line leading to a shaded square (male child) .
