Traits are a person’s defining qualities. For instance, their blood type or the colour of their hair. Genes, as well as gene-environment interactions, have a role in phenotyping. Keep in mind that genes are programmed as the signal transmitters in our DNA that define our unique personalities. As a result, a phenotype is the physical expression of a DNA-encoded gene. Occasionally, the terms “phenotype” and “trait” are used interchangeably, and “phenotype” can also refer to a set of traits.
The term “phenotype” simply refers to an observable property. Phenotypes are typically associated with and used to associate variations in DNA sequences across individuals with a trait, such as height, hair colour, or illness. It is critical to remember, however, that environmental variables have an equal, if not greater, effect on phenotypes than genetic factors. Environmental variables, such as the foods consumed, the amount of activity performed, and the amount of tobacco smoked, almost always have a role.
Acquired Traits
An Acquired Trait is the personality trait that develops in an individual as a result of external influences. These qualities are not encoded in the DNA of a live creature and hence cannot be passed on to subsequent generations.
Examples of Acquired Trait
- Learning to ride a bike is a learned skill.
- Acquired qualities include reading books and gaining abilities.
- Acquired behavioural characteristics are frequently observed in tasks such as musical instrument playing and dog training (teaching him tricks).
- Acquired behavioural characteristics can also be observed when a student is studying.
- Scars are another instance of acquired physical characteristics.
- Hormonal changes associated with puberty are another example of acquired characteristics that cannot be passed on to subsequent generations.
- Muscles formed as a result of bodybuilding and exercise are instances of acquired characteristics.
Inherited Traits
These are the characteristics that are passed on from parents to children. Human hereditary features include hair, complexion, eye colour, physical shape, height, and susceptibility to various disorders. Genes determine an individual’s inherited qualities.
Between 25,000 to 35,000 genes are found in a single human cell. These genes are responsible for the characteristics that an individual inherits from his parents.
Gregor Mendel established the concept of hereditary characteristics via his research on the pea plant. He demonstrated that dominant characteristics are those that are evident in the phenotypic, whereas recessive traits are those that are not visible.
Examples of Inherited Traits
- Curly hair, dimples, and other physical characteristics are frequently viewed as hereditary characteristics. These characteristics are passed down via generations. Additionally, these acquired characteristics are under the control of the human person.
- Inheritance may also be a factor in the development of Green/Red Color Blindness. If an adult suffers from colour blindness, the likelihood is that the child will as well.
- Other characteristics like eye colour, skin tone, and blood type are also inherited from a parent to a kid.
- Height is also an inherited feature in some circ*mstances. However, other research suggests that height should not be considered an inherited feature. This is because height is the result of a complex interaction of over 700 genes in the human body. As a result, it is inappropriate to assume height to be inherited by a single gene.
Characteristics of Acquired and Inherited traits
Acquired traits
- Characteristics acquired by organisms during the course of their existence
- Not handed down from generation to generation
Inherited characteristics
- Gene-controlled characteristics.
- Transmitted from generation to generation.
Purchased Characteristics
- Somatics is subject to variation.
- Acquired characteristics established as a result of ambient influences, organ usage and concealment, and specific (conscious) efforts.
- These characteristics grow during the course of an individual’s existence, culminating in that individual’s death.
Example: studying dance, music, and the muscular body of a wrestler.
Conclusion
Traits can be defined as an organism’s observable and distinguishing characteristics. Genes and the environment, as well as their interactions, all impact traits. The genotype is the genetic component of a trait. The phenotype is the genotype’s external manifestation. Acquired qualities are those that an individual accumulates over his or her life. These are not inherited from one generation to the next. On the other hand, hereditary characteristics are present in a person from birth and are handed down through generations. Acquired traits include knowledge, ideas, skills, and weight, whereas hereditary qualities include hair and eye colour, muscle and bone structure, and nose shape.
