What is the most likely mode of inheritance for this pedigree?

The image is a pedigree chart illustrating the family relationships and genetic traits within the Summers family. In this chart:

- **Symbols**: Squares represent males, circles represent females. Shaded symbols indicate individuals exhibiting a specific trait, while unshaded symbols indicate those without the trait.

- **First Generation**:
  - Katherine Summers (female, shaded)
  - Christopher Summers (male, unshaded)

- **Second Generation**:
  - Alex Summers (male, unshaded), son of Katherine and Christopher
  - Scott Summers (male, shaded), son of Katherine and Christopher, married to Jean Grey

- **Third Generation**:
  - Nathan Summers (male, unshaded), son of Scott Summers
  - Rachel Summers (female, unshaded), daughter of Scott Summers and Jean Grey
  - Ruby Summers (female, shaded), daughter of Scott Summers and Jean Grey

The chart shows the inheritance pattern of a trait that appears to be passed from Katherine Summers to her son Scott, and then to his daughter Ruby.
