Using the letter "R" what is the genotype of Nathan Summers? Use the uppercase letter to represent the dominant allele and lowercase letter to represent the recessive allele.

The image is a family pedigree chart. Here's an explanation of its components:

**Pedigree Symbols:**
- Circles represent females.
- Squares represent males.
- Shaded shapes indicate individuals expressing a certain trait; unshaded shapes denote those without the trait.

**Family Members:**
1. **Katherine Summers** (Female): Shaded circle
2. **Christopher Summers** (Male): Unshaded square
3. **Alex Summers** (Male): Unshaded square
4. **Scott Summers** (Male): Shaded square
5. **Jean Grey** (Female): Shaded circle
6. **Nathan Summers** (Male): Unshaded square
7. **Rachel Summers** (Female): Unshaded circle
8. **Ruby Summers** (Female): Shaded circle

**Connections:**
- Katherine and Christopher are parents to Alex and Scott.
- Scott is married to Jean Grey.
- Scott and Jean have three children: Nathan, Rachel, and Ruby. 

The shading pattern suggests the pedigree follows a genetic trait.
