WordDefinition
DNADNA, or deoxyribonucleic acid, is a molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all living organisms.
RNARNA, or ribonucleic acid, is a molecule essential for various cellular processes, such as protein synthesis, gene regulation, and cell signaling.
geneA gene is a specific sequence of DNA that contains the instructions for producing a functional product, such as a protein.
mutationA mutation is a permanent change in the DNA sequence that can result in altered gene function or protein production.
chromosomeA chromosome is a thread-like structure composed of DNA and proteins found in the nucleus of a cell. It carries genetic information.
genetic codeGenetic code refers to the specific sequence of nucleotides in DNA that determines the sequence of amino acids in proteins.
nucleotideA nucleotide is the basic building block of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.
proteinProteins are large biomolecules consisting of amino acids that perform various functions in the body, including structural and enzymatic roles.
Population geneticsPopulation genetics is the study of genetic variation and evolutionary processes within populations, focusing on how genes are distributed and change over time.
gene flowGene flow is the transfer of genetic material between populations, leading to genetic mixing and influencing the overall genetic diversity.
genetic driftGenetic drift is the random fluctuation in allele frequencies within a population, leading to changes in genetic diversity over time.
allele frequencyAllele frequency refers to the proportion of a specific allele in a population, calculated as the number of that allele divided by the total number of alleles.
genetic variationGenetic variation refers to the diversity of alleles and genotypes within a population, contributing to evolution and adaptation.
Hardy-Weinberg equilibriumHardy-Weinberg equilibrium is a principle stating that allele frequencies in a population will remain constant over generations in the absence of evolutionary forces.
evolutionary forcesEvolutionary forces refer to the processes, such as natural selection, genetic drift, mutation, and gene flow, that drive changes in populations over time.
GenotypeGenotype refers to the genetic makeup of an individual, including the specific combination of alleles present in their DNA.
PhenotypeThe physical characteristics or traits of an organism that result from the interaction between its genetic makeup and the environment.
MutationA mutation in Medical Genetics refers to a change in the DNA sequence that can lead to genetic disorders.
InheritanceInheritance in medical genetics refers to the passing of genetic traits or conditions from parents to offspring through DNA.
Genetic testingGenetic testing is a medical test that looks for changes or variations in an individual's genes, chromosomes, or proteins.
ChromosomesChromosomes are thread-like structures made of DNA and proteins found in the nucleus of cells, carrying genetic information.
Gene therapyGene therapy is a medical procedure that involves modifying a person's genes to treat or prevent disease.
PedigreePedigree in medical genetics refers to a diagram showing the genetic relationships among individuals in a family over generations.
EvolutionEvolution in evolutionary genetics refers to the change in allele frequencies in a population over generations due to natural selection.
GeneticsGenetics in Evolutionary Genetics refers to the study of how genetic variation and inheritance mechanisms contribute to evolutionary processes.
Natural SelectionNatural selection is the process by which organisms better adapted to their environment tend to survive and reproduce more successfully.
MutationMutation refers to a change in the DNA sequence of an organism, which can result in new genetic variations in populations.
AdaptationAdaptation in evolutionary genetics refers to the process by which a population evolves traits that enhance survival and reproduction.
Population GeneticsPopulation genetics is the study of genetic variation within populations and how evolutionary forces such as natural selection and genetic drift shape this variation.
Gene FlowGene flow is the transfer of genetic material between populations, which can lead to increased genetic diversity and reduced genetic differentiation.
PhylogeneticsPhylogenetics is the study of evolutionary relationships among organisms, typically using genetic data to construct evolutionary trees or phylogenies.
GenotypeGenotype refers to an individual's genetic makeup, including specific genes and alleles that influence behavioral traits and tendencies.
PhenotypePhenotype refers to the observable characteristics or traits of an organism, influenced by both genetic and environmental factors.
HeritabilityHeritability refers to the extent to which individual differences in behavior can be attributed to genetic factors rather than environmental influences.
PolygenicPolygenic refers to traits influenced by multiple genes, each contributing a small effect, in the field of behavioral genetics.
Behavioral traitsBehavioral traits in the context of Behavioral Genetics refer to observable characteristics influenced by genetic factors and environmental interactions.
Gene-environment interactionsGene-environment interactions refer to the complex interplay between genetics and environmental factors in shaping an individual's behavior and traits.
Twin studiesTwin studies in Behavioral Genetics involve comparing the similarities and differences in traits between identical and fraternal twins.
EpigeneticsEpigenetics is the study of changes in gene expression caused by environmental factors, rather than alterations to the genetic code.
DNA methylationDNA methylation is an epigenetic process where methyl groups are added to DNA molecules, affecting gene expression without altering the DNA sequence.
Histone modificationHistone modification refers to chemical alterations made to histone proteins that can affect gene expression and chromatin structure.
Gene expressionGene expression refers to the process by which information from a gene is used to create a functional product.
EpigenomeThe epigenome refers to the complete set of chemical compounds that modify the DNA and regulate gene expression.
Chromatin remodelingChromatin remodeling refers to the dynamic alteration of the structure of chromatin that allows or restricts access to DNA for transcription.
Epigenetic inheritanceEpigenetic inheritance is the transmission of changes in gene expression patterns across generations without alterations in the DNA sequence.
