Examples of genetics in the following topics:
-
- Although environment also plays an important role, genetics influence human intelligence and our capacity to learn in many ways.
- While environmental influences play a large role, our ability to learn is also largely shaped by genetics.
- The occurrence of neurobehavioral disorders is influenced by both genetic and non-genetic factors, and the genes directly associated with these disorders are often unknown.
- It may even be possible to develop specific approaches to help individual students with different genetic predispositions more effectively.
- Discuss the role genetics play in our cognition and our ability to learn.
-
- To a large extent, who we are and how we behave is a result of our genetic makeup.
- Behavioral genetics studies heritability of behavioral traits, and it overlaps with genetics, psychology, and ethology (the scientific study of human and animal behavior).
- Genetics plays a large role in when and how learning, growing, and development occurs.
- Classical, or Mendelian, genetics examines how genes are passed from one generation to the next, as well as how the presence or absence of a gene can be determined via sexual reproduction.
- Gregor Mendel is known as the father of the field of genetics, and his work with plant hybridization (specifically pea plants) demonstrated that certain traits follow particular patterns.
-
- Known as our "genetic code," it is shaped like a double helix, made of sequences of nucleic acids attached to a sugar phosphate backbone.
- Some genetic traits are linked to a person's sex and therefore passed on by the sex chromosomes.
- The autosomes contain the remainder of a person's genetic information.
- Chromosomal and genetic manipulation are controversial topics.
- By studying chromosomes and genes, scientists are able to determine the genetic basis for many diseases.
-
- The biological perspective on personality emphasizes the influence of the brain and genetic factors on personality.
- This research can include the investigation of anatomical, chemical, or genetic influences and is primarily accomplished through correlating personality traits with scientific data from experimental methods such as brain imaging and molecular genetics.
- The field of behavioral genetics focuses on the relationship between genes and behavior and has given psychologists a glimpse of the link between genetics and personality.
- A large part of the evidence collected linking genetics and the environment to personality comes from twin studies, which compare levels of similarity in personality between genetically identical twins.
- In the field of behavioral genetics, the Minnesota Study of Twins Reared Apart—a well-known study of the genetic basis for personality—conducted research with twins from 1979 to 1999.
-
- Behavior can influence genetic expression in humans and animals by activating or deactivating genes.
- Behavior can have an impact on genetic makeup, even as early as the prenatal period.
- Addiction is thought to have a genetic component, which may or may not be caused by a genetic mutation resulting from drug or alcohol use.
- For example, in Himalayan rabbits, the genetic expressions of fur, skin, and eyes are regulated by temperature.
- Light exposure also influences genetic expression.
-
- Human intelligence is shaped by both internal genetic factors and external environmental circumstances.
- The natural genetic make-up of the body interacts with environment from the moment of conception.
- While extreme genetic or environmental conditions can predominate behavior in some rare cases, these two factors usually work together to produce individual intelligence.
- However, certain single-gene genetic disorders can severely affect intelligence.
- And like most traits, the occurrence of neurobehavioral disorders is influenced by both genetic and non-genetic factors, and the genes directly associated with these disorders are often unknown.
-
- Genetic expression can be influenced by various social factors, as well as environmental factors, from light and temperature to exposure to chemicals.
- The color of a person's skin is largely genetic, but the influence of the environment will affect these genes in different ways.
- It is relatively unclear whether the genetic or environmental factors had more to do with the child's development.
- In active gene-environment correlation, the person's genetic makeup may lead them to select particular environments.
- Identical twins share the same genotype, meaning their genetic makeup is the same.
-
- Developmental psychology seeks to understand the influence of genetics (nature) and environment (nurture) on human development.
- Natural human behavior is seen as the result of already-present biological factors, such as genetic code.
- Is it because of genetic similarity, or the result of the early childhood environment and what children learn from their parents?
- We are all born with specific genetic traits inherited from our parents, such as eye color, height, and certain personality traits.
- Trait B shows a high heritability, since the correlation of the trait rises sharply with the degree of genetic similarity.
-
- Prenatal development is the process that occurs during the 40 weeks prior to the birth of a child, and is heavily influenced by genetics.
- Chromosomes are genetic material that determines many things about a person, such as eye and hair color, biological sex, and personality traits.
- DNA, or deoxyribonucleic acid, is responsible for the transmission of genetic material.
- The expression of genetic information in a given cell or organism is neither random nor fully pre-programmed.
- For this reason, genetics play a particularly important role in prenatal development.
-
- Biological influences on health and illness and include genetics, infections, physical trauma, nutrition, hormones, and toxins.
- Many disorders have an inherited genetic vulnerability.
- Instead, certain non-biological (i.e., environmental) factors play a role in the expression of the disorder in those with a pre-existing genetic risk.
- Individuals with a genetic vulnerability may be more likely to display negative thinking that puts them at risk for depression.
- Specifically, research on epigenetics suggests that the environment can
actually alter an individual's genetic makeup.
