Most of the traits we ascribe to a person’s personality were acquired over the course of evolutionary time. Some people are born with a trait, while other individuals acquire a trait during their lifetime. The process of acquiring a trait may have begun during the formation of an organism, such as in the case of human beings. Alternatively, it may have started after the organism has already developed into a fully functional reproductive form. Either way, the traits we ascribe to a particular person are rooted in the processes that go on throughout an organism’s lifetime.
Traits are mostly passed on between organisms through the genetic material they inherit from their parents or through their relationship to other organisms. In most cases, such behavioral traits are acquired through sexual reproduction. In some cases, traits can be inherited from one generation to the next by means of inheritance through autosomal genes. However, this is the least common route of inheritance for most traits.
Genotype are both terms that apply to the same set of DNA sequences. The genetic code of an organism is composed of DNAletters which repeat within the entire strand of DNA. Different variations of the genetic code are observed between organisms, in terms of their characters, coloration, and other traits. These genetic differences are the basis for the differences in physical and behavioral traits that we ascribe to the various members of a species.
There are three major classes of traits: physical, behavioral, and phenotypic. Physical traits are those that vary from one person to another. This includes such things as eye color, hair color, height, and other such attributes. Behavior traits are those that are controlled by environmental factors, such as motivation and social upbringing. For example, many people are attracted to certain colors or body shapes. These physical traits are called phenotypic traits.
In order to understand the meaning of what traits are, it is important to know what they consist of. All three classifications of traits have different traits that result from the same genes. In reality, however, there are two traits that are commonly referred to as dominant, and other ones that are considered non-dominant. Dominant traits, as the name suggests, are passed on from one generation to the next by the members of one sex only.
Non-dominant traits, however, are the opposite of dominant ones. They occur in both humans and animals and are caused by the reverse processes that dominate in nature. Non-dominant traits in the human species, then, can be divided into three categories: independent, incomplete, and recessive. Independently acquired traits are those passed on by both parents, whereas incomplete traits are those that must be acquired through a specific gene mutation, usually from one of the parents.
Characteristics of A Trait
An example of an independently acquired trait refers to eye color, which can be either red or green. The particular individual who acquires this trait does not have the mutation that changes its color. Similarly, a person who inherits the blue-eyed trait can still be able to produce blue eyes by using the gene that results in blue eyes in some people.
The incomplete trait is the opposite of independent. It is passed on only by one parent and can be acquired or non-acquired, independent of the other parent. One instance of this type of trait is height. People who possess two different sets of chromosomes that result in a variation of only one pair of chromosomes will often have variations in their height.
The third and most common of all the traits is the recessive trait. It is defined as any character trait that is not found in any pair of chromosomes in a person’s body. For example, if an individual has a characteristic like hair color which is determined by only one chromosome, then this individual is said to be having a recessive polygenic character.
