Allele
An allele, or allelomorph, is a variant of the sequence of nucleotides at a particular location, or locus, on a DNA molecule.
See Locus (genetics) and Allele
Association mapping
In genetics, association mapping, also known as "linkage disequilibrium mapping", is a method of mapping quantitative trait loci (QTLs) that takes advantage of historic linkage disequilibrium to link phenotypes (observable characteristics) to genotypes (the genetic constitution of organisms), uncovering genetic associations.
See Locus (genetics) and Association mapping
Centromere
The centromere links a pair of sister chromatids together during cell division. Locus (genetics) and centromere are chromosomes.
See Locus (genetics) and Centromere
Chromosomal translocation
In genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes.
See Locus (genetics) and Chromosomal translocation
Chromosome
A chromosome is a package of DNA with part or all of the genetic material of an organism. Locus (genetics) and chromosome are chromosomes.
See Locus (genetics) and Chromosome
Chromosome 3
Chromosome 3 is one of the 23 pairs of chromosomes in humans.
See Locus (genetics) and Chromosome 3
Cytogenetic notation
The following table summarizes symbols and abbreviations used in cytogenetics.
See Locus (genetics) and Cytogenetic notation
Euchromatin
Euchromatin (also called "open chromatin") is a lightly packed form of chromatin (DNA, RNA, and protein) that is enriched in genes, and is often (but not always) under active transcription.
See Locus (genetics) and Euchromatin
G banding
G-banding, G banding or Giemsa banding is a technique used in cytogenetics to produce a visible karyotype by staining condensed chromosomes. Locus (genetics) and g banding are chromosomes.
See Locus (genetics) and G banding
Gene
In biology, the word gene has two meanings.
Gene mapping
Gene mapping or genome mapping describes the methods used to identify the location of a gene on a chromosome and the distances between genes. Locus (genetics) and gene mapping are genetics.
See Locus (genetics) and Gene mapping
Genetic marker
A genetic marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species.
See Locus (genetics) and Genetic marker
Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.
See Locus (genetics) and Genetics
Genome
In the fields of molecular biology and genetics, a genome is all the genetic information of an organism.
See Locus (genetics) and Genome
Giemsa stain
Giemsa stain, named after German chemist and bacteriologist Gustav Giemsa, is a nucleic acid stain used in cytogenetics and for the histopathological diagnosis of malaria and other parasites.
See Locus (genetics) and Giemsa stain
Heterochromatin
Heterochromatin is a tightly packed form of DNA or condensed DNA, which comes in multiple varieties.
See Locus (genetics) and Heterochromatin
International System for Human Cytogenomic Nomenclature
The International System for Human Cytogenomic Nomenclature (previously International System for Human Cytogenetic Nomenclature), ISCN in short, is an international standard for human chromosome nomenclature, which includes band names, symbols and abbreviated terms used in the description of human chromosome and chromosome abnormalities.
See Locus (genetics) and International System for Human Cytogenomic Nomenclature
Karyotype
A karyotype is the general appearance of the complete set of chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Locus (genetics) and karyotype are chromosomes.
See Locus (genetics) and Karyotype
Microscope
A microscope is a laboratory instrument used to examine objects that are too small to be seen by the naked eye.
See Locus (genetics) and Microscope
National Cancer Institute
The National Cancer Institute (NCI) coordinates the United States National Cancer Program and is part of the National Institutes of Health (NIH), which is one of eleven agencies that are part of the U.S. Department of Health and Human Services.
See Locus (genetics) and National Cancer Institute
National Center for Biotechnology Information
The National Center for Biotechnology Information (NCBI) is part of the United States National Library of Medicine (NLM), a branch of the National Institutes of Health (NIH).
See Locus (genetics) and National Center for Biotechnology Information
Null allele
A null allele is a nonfunctional allele (a variant of a gene) caused by a genetic mutation.
See Locus (genetics) and Null allele
Oculocutaneous albinism type I
Oculocutaneous albinism type I or type 1A is form of the autosomal recessive condition oculocutaneous albinism that is caused by a dysfunction in the gene for tyrosinase (symbol TYR or OCA1).
See Locus (genetics) and Oculocutaneous albinism type I
Phenotype
In genetics, the phenotype is the set of observable characteristics or traits of an organism.
See Locus (genetics) and Phenotype
Phenotypic trait
A phenotypic trait, simply trait, or character state is a distinct variant of a phenotypic characteristic of an organism; it may be either inherited or determined environmentally, but typically occurs as a combination of the two.
See Locus (genetics) and Phenotypic trait
Ploidy
Ploidy is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes.
See Locus (genetics) and Ploidy
Polyploidy
Polyploidy is a condition in which the cells of an organism have more than one pair of (homologous) chromosomes.
See Locus (genetics) and Polyploidy
Telomere
A telomere is a region of repetitive nucleotide sequences associated with specialized proteins at the ends of linear chromosomes (see Sequences). Locus (genetics) and telomere are chromosomes.
See Locus (genetics) and Telomere
Zygosity
Zygosity (the noun, zygote, is from the Greek "yoked," from "yoke") is the degree to which both copies of a chromosome or gene have the same genetic sequence.
See Locus (genetics) and Zygosity
