Gordon Allport's trait theory was influenced by his study of personality and his belief that traits could be used to categorize and describe individual differences. He was also influenced by the work of Sigmund Freud and Carl Jung, as well as by his own clinical observations of personality. Additionally, Allport was influenced by his dissatisfaction with earlier trait theories that he felt were too broad and lacking in specificity.
This condition is known as polygenic inheritance. It involves multiple genes contributing to a trait, and the expression of these genes can be influenced by environmental factors. The combination of genetic and environmental influences leads to a wide range of variation in the trait.
One example of a sexually influenced trait in humans would be haemophilia. The gene responsible for haemophilia is located on the X chromosome, and if a man receives a gene from his mother (men's X chromosomes always come from their mother) that is positive for this trait, he will exhibit haemophilia. Women must have two X chromosomes that are positive for haemophilia in order to exhibit the trait, because it is a recessive gene.
Multifactorial polygenic threshold theory proposes that complex traits are influenced by both genetic and environmental factors. It suggests that multiple genes contribute to the expression of a trait, and a certain threshold of genetic and environmental factors must be reached to manifest the phenotype. This theory is often used to explain the inheritance of complex traits such as height, intelligence, and susceptibility to diseases.
An example of an epigenetic trait is the inheritance of coat color in mice. This trait can be influenced by epigenetic modifications such as DNA methylation, which can be passed down from one generation to the next without changes to the underlying DNA sequence.
Eye color is an example of a trait that is typically determined by genetic inheritance, but can also be temporarily influenced by wearing colored contact lenses. This demonstrates how environmental factors can override genetic traits.
Gordon Allport and Raymond Cattell are two psychologists who are most commonly associated with the trait theory of personality. They proposed that personality can be understood through identifying and measuring specific traits that individuals possess.
Gordon Allport is known for describing personality in terms of enduring traits. He emphasized that these traits are consistent patterns of thoughts, feelings, and behaviors that influence how individuals react to various situations. Allport's approach laid the groundwork for trait theory in psychology, highlighting the importance of individual differences in personality.

Major perspectives in personality, such as trait theory and psychoanalytic theory, have influenced aspects of everyday life in modern society by shaping how individuals understand themselves and others. For example, trait theory has led to the development of personality assessments used in education and workplace settings, while psychoanalytic theory has influenced the fields of therapy and counseling by emphasizing the role of unconscious processes in behavior. Overall, these perspectives help individuals navigate social interactions, relationships, and personal development.

Trait that is controlled by many genes and is also influenced by the environment.

A fundamental concept of trait theory
Trait theory refers to the conceptual framework that focuses on identifying and measuring individual personality characteristics, known as traits, that are stable over time and influence behavior. In contrast, the trait approach is the practical application of this theory, involving the assessment and analysis of these traits to understand and predict individual behavior in various contexts. While trait theory provides the foundational understanding of personality traits, the trait approach involves utilizing this understanding in real-world settings, such as in psychological assessments or research.
An example of a sex-influenced trait is male pattern baldness, where the expression of the trait is influenced by sex hormones. In males, high levels of dihydrotestosterone can lead to hair loss, while females with the same genetic predisposition are less likely to be affected. This trait is influenced by sex hormones but not exclusively linked to a specific sex.
Height in considered a polygenic trait because your height is influenced by multiple genes.
Trait Theory as I've learned it is more for leadership, in which "they" attempt to identify specific characteristics associated with success (could be physical, mental, personality, etc.). Basically trait theory says "he/she was born to do this". So say you see a tall kid, and think "he should be a great basketball player". Well, guess that's some stereotyping, but also applicable to trait theory. I personally buy into Process Theory more than Trait Theory, or at the very least a combination of the two.
