Dominant vs. Recessive Traits in Chicken Breeds
Jun 18, 2025 • Genetics • 7 minute read
Genetics play a powerful role in determining how a chicken looks and behaves. Whether you're a breeder or a curious chicken owner, understanding dominant and recessive traits can help you predict what offspring may look like and how certain traits are passed down through generations. In this article, we explain the difference between dominant and recessive traits and how they show up in common chicken breeds.
What Are Dominant and Recessive Traits
Dominant traits are those that appear even when only one copy of the gene is present. If a chicken inherits a dominant gene from either parent, that trait will likely be expressed.
Recessive traits, on the other hand, only show up when both copies of the gene are the same. This means the chicken must inherit the recessive gene from both parents for the trait to appear.
Understanding which traits are dominant and which are recessive is key to predicting how different features may appear in chicks.

Examples of Dominant Traits in Chickens
A common example of a dominant trait is the single comb. Chickens with even one copy of the single comb gene will show this feature, making it a useful marker in breeding.
Other dominant traits include yellow leg color, clean (non-feathered) legs, and barred feather patterns like those found in Plymouth Rocks. These traits tend to appear consistently in mixed or pure breeds when the dominant gene is present.
Examples of Recessive Traits and How They Work
Recessive traits often stay hidden for generations and only appear when both parents carry the gene. One example is the pea comb, which is recessive to the single comb and requires two copies to be visible.
Feathered legs are another recessive trait. Even if a bird carries the gene, it won’t show unless both gene copies are present.
Some feather colors, such as lavender or blue, are also linked to recessive genes. Breeding for these traits requires careful pairing and knowledge of each bird’s genetic background.

How to Use Genetics in Breeding Decisions
Knowing which traits are dominant or recessive helps breeders make informed decisions when selecting breeding pairs. It allows for more predictable results and helps maintain or improve specific breed features.
By tracking lineage and understanding gene combinations, breeders can work toward goals such as improving feather patterns, preserving rare colors, or reducing unwanted traits.
Why Recessive Traits Still Matter
Even though recessive traits are harder to spot, they are just as important in shaping a breed’s characteristics. These hidden genes can resurface in later generations, sometimes unexpectedly.
For example, two chickens with dominant visible traits might still produce offspring with recessive features if both carry the underlying genes.
This is why even experienced breeders can be surprised by the occasional unexpected comb type, leg color, or feather style.
Maintaining detailed breeding records helps identify carriers of recessive traits and plan future matings more accurately.

Conclusion: Understanding Inheritance for Better Breeding
Learning the difference between dominant and recessive traits helps anyone interested in chicken breeding or identification make better sense of what they see in the coop.
Genetics may seem complex at first, but even a basic understanding of inheritance patterns can go a long way in predicting how traits will appear and ensuring the health and consistency of future generations.
