Molecular Genetics |
Research focused on the identification of particular genes to describe how these genes work within the cell. |
|
Behavioral Genetics |
Research to determine the degree of genetic basis for a behavior, trait, or ability. |
|
Behavioral Genomics |
A measure of the extent to which genes determine a particular behavior or characteristic. |
|
Monozygotic Twins |
One zygote splits into two, and have identical DNA. |
|
Dizygotic twins |
Two eggs are fertilized by two sperm and have the same genetic similarity as siblings. |
|
Phenotype |
A person's bodily traits and characteristics.
|
|
Genotype |
All the genes that make up a human being, or the specific genes at a particular location on a chromosome.
|
|
Dominant Genes |
Genes that are usually expressed in the phenotype.
|
|
Recessive Genes |
Genes that are generally not expressed in the phenotype unless paired with another recessive gene.
|
|
Polygenetic Inheritance |
Many genes interact together to produce a particular trait or behavior. |
|
Pleiotropic Effects |
Any single gene can affect many different traits. |
|
Multifactorial Inheritance Disorders |
The interaction of many genes that also interact with environmental influences. |
|
Gene Therapy |
Treatment of specific genetic disorders through implanting or disabling certain genes. |
|
Canalization |
The degree to which the expression of a gene is influenced by the environment. |
|
Epigenetics |
A system by which genes are activated or silenced in response to events or circumstances in the individual's environment. |
|
Passive Gene Environment Interaction |
A child's family shares genetically determined abilities and interests. |
|
Active Gene Environment Interaction |
One's genetic endowment becomes a driving force for children to seek out experiences that fit their genetic endowments. |
|
Evocative Gene Environment Interaction |
Children's genetic endowment causes them to act in a way that draws out or evokes certain responses from those around them. |
|
Gene |
A segment of DNA on a chromosome that creates proteins that are the basis for the body's development and functioning. |
|
Genome |
All of a person's genes, including those that are active and those that are silent. |
|
Genome-Wide Association |
A system that allows scientists to examine the whole human genome at once. |
|
Heritability |
A measure of the extent to which genes determine a particular behavior or characteristic. |
|
Nucleotides |
Organic molecules containing a chemical base, a phosphate group, and a sugar molecule. |
|
Fertilization |
The union of a father's sperm and a mother's egg to produce a zygote. |
|
Zygote |
A fertilized egg. |
|
Chromosomes |
The strands of genes that constitute the human genetic endowment. |
|
Mutations |
Changes that occur in the structure of a gene. |
|
Polygenic Inheritance |
Numerous genes may interact to promote any particular trait or behavior. |
|
Pleiotropic Effects |
The many different influences any single gene may have. |
|
Generalist Genes |
Genes that affect many related abilities. |
|
Single Gene Disorders |
Genetic disorders caused by a single recessive gene or mutation. |
|
Chromosomal Disorders |
Disorders that result when too many or too few chromosomes are formed or when there is a change in the structure of the chromosome caused by breakage. |
|
Multifactorial Inheritance Disorders |
Disorders that result from the interaction of many genes in interaction with environmental influences. |
