The Targaryen Legacy and a Confusing Hair Color
For fans of HBO's epic fantasy series Game of Thrones, the lineage of Jon Snow has always been a central mystery. While his mother was revealed to be Lyanna Stark, his father was eventually unveiled as none other than Aegon Targaryen, also known as Jon Snow himself. This revelation, often referred to as "R+L=J," sent shockwaves through the fandom. However, a persistent question lingered: if Jon is a Targaryen, why does he have dark, almost black hair, when the Targaryens are famously known for their striking silver-white or platinum blonde locks?
The Targaryen Trait: Silver Hair and Purple Eyes
The Targaryen family tree is filled with individuals possessing distinct physical characteristics, the most prominent being their Targaryen hair color. This unique shade, often described as silver, platinum blonde, or even white, is a hallmark of their bloodline. This trait is directly linked to a genetic mutation, a recessive gene that, when passed down through generations, manifests in this distinctive coloration. Coupled with this often comes a striking violet or indigo eye color, another signifier of their Valyrian ancestry.
Characters like Daenerys Targaryen, Viserys Targaryen, and Aerys II Targaryen all proudly displayed these signature features. Their silver hair was a constant visual reminder of their ancient and powerful lineage, a lineage that once ruled the Seven Kingdoms with dragons at their command.
Enter the Starks: A Powerful Influence
Jon Snow's mother, Lyanna Stark, hailed from the North and was a prominent member of House Stark. The Starks are characterized by their dark hair, typically brown or black, and grey or blue eyes. These are common traits in the populations of the North, reflecting the region's distinct environment and genetic makeup.
When discussing genetics, it's crucial to understand the concepts of dominant and recessive genes. A dominant gene will express its trait even if only one copy is present, while a recessive gene needs two copies to manifest its characteristic. In the case of hair color, darker shades are generally dominant over lighter shades like the Targaryen's silver hair.
The Genetic Interplay: How Jon Got His Hair Color
Here's where the genetic puzzle pieces begin to fit for Jon Snow:
- Targaryen Recessive Gene: The silver hair of the Targaryens is a result of a recessive gene. For a Targaryen to have silver hair, they must inherit this gene from both parents, or in some instances, specific genetic combinations can still lead to the trait.
- Stark Dominant Gene: Lyanna Stark carried the genes for dark hair, which are generally dominant.
- The Combination: When Lyanna Stark and Rhaegar Targaryen (Jon's parents) conceived Jon, Jon inherited genes from both. He inherited the recessive silver hair gene from his father, Rhaegar, but he also inherited the dominant dark hair gene from his mother, Lyanna.
Because the dark hair gene is dominant over the silver hair gene, Jon's phenotype (his observable physical traits) expressed the dark hair. Even though he carries the Targaryen gene for silver hair, the presence of the dominant Stark gene masks its expression, resulting in his iconic dark, brooding look.
What About His Eyes?
While his hair color leans heavily towards his Stark heritage, some fans have pointed to subtle hints of Targaryen influence in Jon's appearance, particularly in his eyes. Though often described as grey, there are moments in the series where his eyes appear to have a darker, almost purplish hue, especially under certain lighting or emotional duress. This could be a subtle nod to his Targaryen ancestry, a less pronounced manifestation of the Valyrian blood running through his veins.
The intricacies of genetics mean that not every trait will be expressed equally. It's entirely possible for a recessive gene to be present and carried, influencing other genetic expressions or showing up in less obvious ways. In Jon's case, his dominant Stark genes largely dictated his hair color, but the Targaryen influence might still be there, whispering in the shade of his eyes.
"He has the look of the Starks, yes. But there's a fire in him too. A fire that comes from beyond the Wall, and from the blood of dragons." - Maester Aemon
The Significance of His Appearance
Jon Snow's appearance is a constant visual metaphor for his dual heritage. He embodies the honor and stoicism of the Starks, yet he possesses a hidden strength and destiny tied to the Targaryens. His dark hair, initially a symbol of his perceived bastardy and his Stark identity, becomes a point of curiosity and debate once his true parentage is revealed. It serves as a reminder that identity is complex and can be shaped by both obvious and hidden influences.
Conclusion: A Multilayered Legacy
In essence, Jon Snow's dark hair is a testament to the power of dominant genes in genetics. While he is undeniably a Targaryen, his mother's Stark bloodline significantly influenced his most prominent physical characteristic. This genetic interplay not only explains his hair color but also adds another layer of depth to his already compelling character, making him a true fusion of two of Westeros' most storied houses.
Frequently Asked Questions (FAQ)
How did Jon Snow inherit Targaryen genes if his father kept him hidden?
Jon's father, Rhaegar Targaryen, ensured his son was hidden and raised as Ned Stark's bastard to protect him from King Robert Baratheon's wrath. However, the inheritance of genes occurs at conception, regardless of whether the parents are together or if the child is publicly acknowledged. Rhaegar and Lyanna conceived Jon, and thus, Jon inherited genetic material from both of them.
Why didn't Jon Snow have the typical silver Targaryen hair?
Jon Snow's hair is dark because the genes for dark hair are generally dominant over the genes for silver hair, which are recessive. He inherited the recessive silver hair gene from his Targaryen father, Rhaegar, but he also inherited the dominant dark hair gene from his Stark mother, Lyanna. The dominant gene masked the expression of the recessive one, resulting in dark hair.
Are there any other physical traits that show Jon's Targaryen heritage?
While his hair color is decidedly Stark, some fans believe there are subtle hints of his Targaryen blood. His eyes, often described as grey, have been seen to have a darker, almost purplish hue in certain lighting or emotional moments, which could be a less pronounced manifestation of the Valyrian violet eyes.
Does Jon Snow's hair color change his claim to the Iron Throne?
No, Jon Snow's hair color does not affect his claim to the Iron Throne. His claim is based on his true parentage as Aegon Targaryen, the son of Rhaegar Targaryen and Lyanna Stark, making him a direct descendant of the Targaryen dynasty. The expression of genes for physical traits like hair color is separate from his right to rule.
