Examples of gene in the following topics:
-
- Behavior can influence genetic expression in humans and animals by activating or deactivating genes.
- This has led to the discovery of specific genes, such as those that influence addictive behaviors.
- Exposure to drugs and alcohol can also influence the genes of children and adults.
- Temperature exposure can affect gene expression.
- Exposure to cold temperatures activates pigment-producing genes in the rabbit's extremities.
-
- Long-standing debates have taken place over the idea of which factor is more important, genes or environment.
- Gene-environment correlations, known as rGE, can be explained in 3 particular ways—passive, evocative, or active.
- Evocative gene-environment correlation happens when an individual's (heritable) behavior evokes an environmental response.
- In active gene-environment correlation, the person's genetic makeup may lead them to select particular environments.
- Adoption and twin studies can help make sense of the influence of genes and the environment.
-
- The influence of genes on behavior has been well established in the scientific community.
- While genes do not determine behavior, they play a huge role in what we do and why we do it.
- 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.
- Genes can be manipulated by selective breeding, which can have an enormous impact on behavior.
-
- Prenatal development is highly influenced by the inheritance, expression, and regulation of genes.
- Genes can either be dominant or recessive, meaning they can either be expressed or hidden.
- Gene regulation is the process by which cells differentiate.
- Among other things, it is the process in which a cell determines which genes it will express and when.
- Some mutations of the genes can result in conditions such as Down Syndrome or Turner's Syndrome.
-
- Environmental inputs can affect the expression of genes, a relationship called gene-environment interaction.
- Genes and the environment work together, communicating back and forth to create traits.
- This chart illustrates three patterns one might see when studying the influence of genes and environment on individual traits.
- This chart illustrates three patterns one might see when studying the influence of genes and environment on individual traits.
- Evaluate the reciprocal impacts between genes and the environment and the nature vs. nurture debate
-
- Chromosomes also contain genes, most of which are made up of DNA and RNA.
- Genes are subsections of DNA molecules linked together that create a particular characteristic.
- Chromosomes are made up of a variety of gene sequences.
- By studying chromosomes and genes, scientists are able to determine the genetic basis for many diseases.
-
- Recent research shows that under normal circumstances, intelligence involves multiple genes; however certain single-gene genetic disorders can severely affect intelligence.
- 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.
- While experts believe the genetic cause for the syndrome is a lack of genes in the 21st chromosome, the gene(s) responsible for the cognitive symptoms have yet to be discovered.
-
- A gene is the unit of heredity by which a biological trait is passed down through generations of human beings.
- This is thought to occur through human interaction with external circumstances, whereby people with different genes seek out different environments.
- As mentioned, under normal circumstances intelligence involves multiple genes.
- However, certain single-gene genetic disorders can severely affect intelligence.
- While experts believe the genetic cause for Down syndrome is a lack of genes in the 21st chromosome, the gene(s) responsible for the cognitive symptoms have yet to be discovered.
-
- 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.
- It's important to point out that traits are determined not by a single gene, but by a combination of many genes, and also by environmental factors that control whether certain genes are expressed.
- Many personality studies today investigate the activation and expression of genes and how they relate to personality.
- How DNA interacts with the environment determines what part of the DNA code is actually activated within an individual—in other words, which genes will be expressed.
- The expression of inherited genes plays a role in determining personality.
-
- This results in social processes that maximize individuals' genetic fitness, or ability to pass their genes to the next generation.
- Consider the following example: in a population's gene pool, a genotype exists for an infant that is unattached from its mother—it will crawl away and does not have any "love" or other significant attachment to its mother.
- Over many generations, more "attached" infants will survive to mate and pass on their gene for attachment.
- From an evolutionary point of view, behaviors are not made consciously: they are instinctual, and based on what is most advantageous in terms of passing one's genes on to the next generation.
