Allele
An allele is a variant form of a given gene.

Centromere
The centromere is the specialized DNA sequence of a chromosome that links a pair of sister chromatids (a dyad).
New!!: Locus (genetics) and Centromere · See more »
Centrosome
In cell biology, the centrosome (Latin centrum 'center' + Greek sōma 'body') is an organelle that serves as the main microtubule organizing center (MTOC) of the animal cell as well as a regulator of cell-cycle progression.

Chromosomal translocation
In genetics, a chromosome translocation is a chromosome abnormality caused by rearrangement of parts between nonhomologous chromosomes.

Chromosome
A chromosome (from Ancient Greek: χρωμόσωμα, chromosoma, chroma means colour, soma means body) is a DNA molecule with part or all of the genetic material (genome) of an organism.

Chromosome 3
Chromosome 3 is one of the 23 pairs of chromosomes in humans.

G banding
G-banding, G banding, or Giemsa banding is a technique used in cytogenetics to produce a visible karyotype by staining condensed chromosomes.
New!!: Locus (genetics) and G banding · See more »
Gene
In biology, a gene is a sequence of DNA or RNA that codes for a molecule that has a function.
New!!: Locus (genetics) and Gene · See more »
Gene map
Gene maps help describe the spatial arrangement of genes on a chromosome.
New!!: Locus (genetics) and Gene map · See more »
Gene mapping
Gene mapping describes the methods used to identify the locus of a gene and the distances between genes.
New!!: Locus (genetics) and Gene mapping · See more »
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.
New!!: Locus (genetics) and Genetic marker · See more »
Genetics
Genetics is the study of genes, genetic variation, and heredity in living organisms.
New!!: Locus (genetics) and Genetics · See more »
Genome
In the fields of molecular biology and genetics, a genome is the genetic material of an organism.
New!!: Locus (genetics) and Genome · See more »
International System for Human Cytogenetic Nomenclature
The International System for Human Cytogenetic Nomenclature (ISCN) 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.

Karyotype
A karyotype is the number and appearance of chromosomes in the nucleus of a eukaryotic cell.
New!!: Locus (genetics) and Karyotype · See more »
Microscope
A microscope (from the μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small to be seen by the naked eye.

National Cancer Institute
The National Cancer Institute (NCI) 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.

Null allele
A null allele is a nonfunctional copy of a gene caused by a genetic mutation.
New!!: Locus (genetics) and Null allele · See more »
Oculocutaneous albinism type I
Oculocutaneous albinism type I or type 1A (OCA1A or OCAIA) is an autosomal recessive skin disease.
New!!: Locus (genetics) and Oculocutaneous albinism type I · See more »
Phenotypic trait
A phenotypic trait, or simply trait, 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.
New!!: Locus (genetics) and Phenotypic trait · See more »
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.
New!!: Locus (genetics) and Ploidy · See more »
Polyploid
Polyploid cells and organisms are those containing more than two paired (homologous) sets of chromosomes.
New!!: Locus (genetics) and Polyploid · See more »
Telomere
A telomere is a region of repetitive nucleotide sequences at each end of a chromosome, which protects the end of the chromosome from deterioration or from fusion with neighboring chromosomes.
New!!: Locus (genetics) and Telomere · See more »
Zygosity
Zygosity is the degree of similarity of the alleles for a trait in an organism.
