When it comes to discussing traits and characteristics, two terms that are often used interchangeably are “hereditary” and “genetic.” While they may seem similar, there is a distinct difference between the two.
In this section, we will explore the meanings of hereditary and genetic and how they relate to each other. We’ll do this by comparing hereditary vs genetic and discussing their role in determining our physical and biological makeup. Read on.
Comparing Transmission
Hereditary and genetic traits both refer to characteristics that are passed down from parents to offspring. Yet, how they are transmitted differs between the two.
Hereditary Traits
Hereditary traits are those that are inherited through genes from one’s parents. These include physical characteristics such as:
- hair color
- eye color
- height
This is because of biological traits such as blood type and susceptibility to certain diseases. These traits are determined by a combination of genes from both parents.
Genetic Traits
Genetic traits refer to characteristics that are determined by variations in DNA sequences called alleles. These can be inherited from both parents. They may also be influenced by environmental factors.
Genetic traits can manifest in physical features. But, they can also affect things like personality and behavior. For example, someone may have a genetic predisposition to being introverted or having a certain temperament.
In any DNA report, genetic traits are often highlighted. This is because they can provide valuable information about potential health risks or predispositions towards certain conditions.
Along with a dna test for success, understanding genetic traits can help individuals make informed decisions about their lifestyle and health.
Understanding Inheritance
It’s also important to note that both play a significant role in our physical and biological makeup. Take note that inheritance is not a simple one-to-one process. It is rather a complex combination of various genes and alleles.
Inheritance Patterns
As mentioned earlier, hereditary traits follow Mendelian inheritance patterns. This means that they are determined by dominant and recessive genes. They have dominant genes that are more likely to be expressed over recessive ones.
Genetic traits can exhibit different inheritance patterns such as polygenic inheritance. This is where multiple genes contribute to a trait or incomplete dominance. This is where neither gene is dominant and the resulting trait is a blend of the two.
Nature vs. Nurture
It’s also worth noting that while genetics play a major role in our traits, our environment and experiences can also influence the expression of certain characteristics. This is known as the nature vs nurture debate.
For example, someone may have a genetic predisposition to being tall.
But, if they grow up in an environment with poor nutrition or limited access to healthcare, their height may be stunted. This is especially true when compared to someone with the same genetic predisposition who grows up in an optimal environment.
Another example would be looking into a genetic talent for sports, but without the proper training and opportunities, that talent may not be fully developed.
Learn to Compare Hereditary vs Genetic Traits
While hereditary and genetic traits both refer to characteristics that are passed down from parents to offspring, they differ in how they are transmitted and the factors that influence their expression.
Understanding the differences between hereditary vs genetic is crucial. That way, we can comprehend the complex nature of our physical and biological makeup.
So remember, the next time you hear someone use these terms interchangeably, you’ll know the distinct differences between hereditary and genetic traits.
