c. IV-2 is unaffected

d. IV-1 is affected 

e. II-2 is unaffected

This image depicts a pedigree chart, which is used to illustrate the inheritance patterns of genetic traits within a family.

In this chart:
- Squares represent males.
- Circles represent females.
- Filled symbols (black) indicate individuals expressing a particular trait.
- Empty symbols (white) indicate individuals who do not express the trait.

Explanation of the chart structure:
1. The first generation at the top includes one male (black square) and one female (white circle). They have one male offspring (black square) who expresses the trait.
2. The second family line begins with one female (white circle) and one male (white square). They have two children: one female (white circle) and one male (white square), neither of whom express the trait.
3. The third generation includes two children from the female of the second generation. It consists of one female (black circle) who expresses the trait and one male (white square) who does not.

Overall, the chart illustrates the transmission of a genetic trait through three generations, with specific individuals exhibiting or not exhibiting the trait.
