DNA – How It Affects Our Traits, Mannerisms, Voice Tones

Ever wonder how much of who we are is determined by our DNA?

Our genetic makeup, influenced by DNA, is the foundation for our inherent traits and tendencies. It significantly shapes our attitudes, beliefs, and behaviours, providing a unique blueprint for how we communicate, problem-solve, connect with others, and navigate life’s challenges. This intricate interplay defines our identity and our interactions with the world.

Genes are essentially the body’s instruction manual, dictating physical attributes much like how codes dictate a system. This information or “codes” from genes let the body know what characteristics a person will have. These characteristics can be physical (from eye and lip shape to nose size) or internal (metabolism rate). They don’t just provide detailed instructions that define our outward appearance but also the internal processes that influence how our bodies function every day.

Isn’t it astonishing how a minuscule DNA strand, measuring just 2.5 nanometers, significantly influences our vocal tone? The FOXP2 gene is a key player in this process, exerting a profound influence on language development and speech. Envision the brain as a bustling control centre filled with specialized workers. Some of these workers are dedicate to speech. Requiring precise instructions for coordinating mouth, tongue, and vocal cord movements. The FOXP2 gene acts as their supervisor, providing essential guidelines for efficient task execution. When functioning optimally, this gene creates a seamless speech plan, directing speech muscles to articulate words clearly.

A familial history of clear speech often correlates with a beneficial FOXP2 variant. If your parents have a version of the FOXP2 gene that helps them talk smoothly, you might inherit that same version, making it easier for you to learn to speak clearly too. However, if there’s a difference in the gene. It might make learning to talk a bit more challenging, similar to how your parents might have experienced it.

Now imagine knowing all of this yet remaining completely oblivious to the connections between your own biological makeup and your parents until the age of 57. Perhaps you’re an introvert growing up in a family of extroverts, or your eye color bears no resemblance to any of your relatives. Switched at Birth: My Life in Someone Else’s World by Frederick J.
