Human Traits and Heredity Human traits are specific characteristics that identify individuals. The parents pass down these through their genes. Some easy-to-identify human traits are height, eye color, hair color, hair type, earlobe attachment and tongue rolling.

Physical characteristics that are most genetically determined include height, weight, tone of voice, tooth decay, athletic ability, and age of death, among others.

Heredity is defined as the characteristics we get genetically from our parents and our relatives before them. An example of heredity is the likelihood that you will have blue eyes. An example of heredity is your possibility of having breast cancer based on family history.

Genes are small sections of the long chain of DNA. They are the basic physical and functional units of heredity. In humans, genes vary in size from a few hundred DNA bases to more than two million bases.

Heredity refers to the genetic heritage passed down by our biological parents. It’s why we look like them! More specifically, it is the transmission of traits from one generation to the next. These traits can be physical, such as eye colour, blood type or a disease, or behavioural.

Truly speaking heredity and environment play an important role in the development of the personality and other qualities in the individual. No person can be born without heredity and genes cannot develop without proper environment. Each trait and response of an individual depends on his heredity and environment.

Heredity is important to all living organisms as it determines which traits are passed from parent to child. Successful traits are more frequently passed along and over time can change a species. Changes in traits can allow organisms to adapt to specific environments for better rates of survival.

Heredity and genetics are directly related. Genetics includes all the traits that you have that are encoded into your genes.

Heredity also plays an important role in shaping one’s personality by placing limits on individuals. Inherited characteristics limit what is possible. They will not determine what a person will do.

As we all know, genes from our parents influence everything from height, weight, eye color, and other physical characteristics, to behavioral patterns in achievement, intelligence and motivation.

The three principles of heredity are dominance, segregation, and independent assortment. The law of dominance describes how different alleles interact…

Genes, via their influences on morphology and physiology, create a framework within which the environment acts to shape the behavior of an individual animal. The environment can affect morphological and physiological development; in turn behavior develops as a result of that animal’s shape and internal workings.

Effects of Heredity on Learning It lays the foundation for the intellectual potential or ability of an individual. Each individual inherits different types of intelligences from their parents. Some inherit analytical intelligence others prowess in creative intelligence and practical intelligences.

Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors. These studies suggest that genetic factors underlie about 50 percent of the difference in intelligence among individuals.

In other words, the controversy involves the extent of contribution as well as the nature of interaction among a variety of genetic and environmental forces.

Both heredity and environment have their share in molding the life and personality of the individual. Heredity is responsible for all the inborn traits, the instincts, emotions, I.Q., reflex action and physical traits. Environment is responsible for the growth and development of the physical, mental and social traits.

Heredity involves traits that are passed down from parents to their children biologically through genes. Environment refers to one’s surroundings.

Syllabus Heredity and Environment and Study Material. Heredity Means: Like presents, like children. Petersons said, “ Heredity may be defined as what one gets from his ancestral stock through his parents.” Environment. Anastasi said, “The Environment is everything that affects the individual except the genes.”

Researchers concluded that “inherited genetic factors make a minor contribution to susceptibility to most types” of cancer. Instead, environmental factors seemed more important. Those factors “encompass everything that is not genetic,” said Heather Spencer Feigelson, Ph.

Heredity: all the traits and properties that are passed along biologically from both parents to child. To some degree this determines your general level of health. You inherit physical traits such as the color of your hair and eyes, shape of your nose and ears, as well as your body type and size.

Both genetics and environment influence personality. Twin studies have found that genetics play a larger role than parental influences when it comes to behavioral outcomes, but non-shared environmental factors play an even bigger role.

ApoE-e3 is the most common allele (a variant of the gene) and is found in more than 50% of the general population….According Kerpedjiev, the top-10 most-studied genes are:

• EGFR;
• VEGFA;
• APOE;
• IL6;
• TGFBI;
• MTHFR;
• ESR1; and,
• AKT1.

Genetics may also control personality, research suggests. Traits like self control, decision making, and sociability. Traits like aggression however, are argued over whether they are genetically determined or not. Some people say that genetic traits are developed through the environment in childhood.

Factors that Influence Our Personality

• Heredity: ADVERTISEMENTS:
• Family background: The socio-economic status of the family, education of the parents, and other family members shape the personality of an individual to a considerable extent.
• Nature of people with whom we interact: ADVERTISEMENTS:
• Culture:

Personalities are characterized in terms of traits, which are relatively enduring characteristics that influence our behaviour across many situations. Personality traits such as introversion, friendliness, conscientiousness, honesty, and helpfulness are important because they help explain consistencies in behaviour.
