genetic phenomena Genetic may refer to: *Genetics, in biology, the science of genes, heredity, and the variation of organisms **Genetic, used as an adjective, refers to genes ***Genetic disorder, any disorder caused by a genetic mutation, whether inherited or de nov ...


consanguinity


founder effect In population genetics, the founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population. It was first fully outlined by Ernst Mayr in 1942, using ...


gene frequency

* –
gene flow In population genetics, gene flow (also known as gene migration or geneflow and allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent a ...
* – genetic drift


gene order


gene pool The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. Description A large gene pool indicates extensive genetic diversity, which is associated with robust populations that can surv ...


genetic load


genomic instability

* –
chromosome instability Chromosomal instability (CIN) is a type of genomic instability in which chromosomes are unstable, such that either whole chromosomes or parts of chromosomes are duplicated or deleted. More specifically, CIN refers to the increase in rate of additio ...
* – chromosome fragility


genotype The genotype of an organism is its complete set of genetic material. Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location. The number of alleles an individual can have in a ...

* – gene dosage * – genetic predisposition to disease * – haplotypes * – heterozygote * – homozygote


hybrid vigor


inheritance patterns

* – anticipation, genetic * – extrachromosomal inheritance * – genes, mitochondrial * – genes, dominant * – genes, recessive * – genes, x-linked * – genes, y-linked * –
multifactorial inheritance A quantitative trait locus (QTL) is a locus (section of DNA) that correlates with variation of a quantitative trait in the phenotype of a population of organisms. QTLs are mapped by identifying which molecular markers (such as SNPs or AFLPs) c ...
* – quantitative trait, heritable


linkage (genetics)

* – linkage disequilibrium * –
lod score Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction. Two genetic markers that are physically near to each other are unlikely to be separ ...


phenotype

* – genetic markers * – penetrance


phylogeny


ploidies

* – aneuploidy * – monosomy * – trisomy * – diploidy * –
haploidy Ploidy () is the number of complete sets of chromosomes in a cell (biology), cell, and hence the number of possible alleles for Autosome, autosomal and Pseudoautosomal region, pseudoautosomal genes. Sets of chromosomes refer to the number of mat ...
* – polyploidy


sequence homology Sequence homology is the biological homology between DNA, RNA, or protein sequences, defined in terms of shared ancestry in the evolutionary history of life. Two segments of DNA can have shared ancestry because of three phenomena: either a spe ...

* – sequence homology, amino acid * – sequence homology, nucleic acid * – synteny


sex ratio


structural homology, protein A protein superfamily is the largest grouping (clade) of proteins for which common ancestry can be inferred (see homology). Usually this common ancestry is inferred from structural alignment and mechanistic similarity, even if no sequence similari ...


variation (genetics)

* – antibody diversity * – antigenic variation * – genetic heterogeneity * – mutation * – allelic imbalance * – loss of heterozygosity * – chromosome deletion * – base pair mismatch * – codon, nonsense * –
chromosome aberrations A chromosomal abnormality, chromosomal anomaly, chromosomal aberration, chromosomal mutation, or chromosomal disorder, is a missing, extra, or irregular portion of chromosomal DNA. These can occur in the form of numerical abnormalities, where ther ...
* – aneuploidy * – monosomy * – trisomy * – chimerism * –
chromosomal instability Chromosomal instability (CIN) is a type of genome instability, genomic instability in which chromosomes are unstable, such that either whole chromosomes or parts of chromosomes are duplicated or deleted. More specifically, CIN refers to the increas ...
* – chromosome fragility * – chromosome breakage * – chromosome deletion * – inversion, chromosome * – isochromosomes * – micronuclei, chromosome-defective * – mosaicism * –
ring chromosomes A ring chromosome is an aberrant chromosome whose ends have fused together to form a ring. Ring chromosomes were first discovered by Lilian Vaughan Morgan in 1926. A ring chromosome is denoted by the symbol ''r'' in human genetics and ''R'' in ''D ...
* – sex chromosome aberrations * – xyy karyotype * – translocation, genetic * – philadelphia chromosome * – uniparental disomy * – dna repeat expansion * – trinucleotide repeat expansion * –
frameshift mutation A frameshift mutation (also called a framing error or a reading frame shift) is a genetic mutation caused by indels ( insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three. Due to the triplet nature ...
* – gene amplification * –
gene duplication Gene duplication (or chromosomal duplication or gene amplification) is a major mechanism through which new genetic material is generated during molecular evolution. It can be defined as any duplication of a region of DNA that contains a gene. ...
* – genomic instability * – germline mutation * – mutation, missense * – point mutation * – sequence deletion * – chromosome deletion * – gene deletion * – suppression, genetic * – polymorphism, genetic * – polymorphism, restriction fragment length * – polymorphism, single-stranded conformational * – polymorphism, single nucleotide ---- The list continues at List of MeSH codes (G14). {{MeSH codes G13
