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.

Euchromatin
Euchromatin 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.

Fungus
A fungus (plural: fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.

Horizontal gene transfer
Horizontal gene transfer (HGT) or lateral gene transfer (LGT) is the movement of genetic material between unicellular and/or multicellular organisms other than by the ("vertical") transmission of DNA from parent to offspring.

Karyotype
A karyotype is the number and appearance of chromosomes in the nucleus of a eukaryotic cell.

Marker chromosome
A marker chromosome (mar) is a small fragment of a chromosome which generally cannot be identified without specialized genomic analysis due to the size of the fragment.

Phytoalexin
Phytoalexins are antimicrobial and often antioxidative substances synthesized de novo by plants that accumulate rapidly at areas of pathogen infection.

Polymorphism (biology)
Polymorphism in biology and zoology is the occurrence of two or more clearly different morphs or forms, also referred to as alternative phenotypes, in the population of a species.

Polyploid
Polyploid cells and organisms are those containing more than two paired (homologous) sets of chromosomes.

Rye
Rye (Secale cereale) is a grass grown extensively as a grain, a cover crop and a forage crop.

Satellite DNA
Satellite DNA consists of very large arrays of tandemly repeating, non-coding DNA.

Species
In biology, a species is the basic unit of classification and a taxonomic rank, as well as a unit of biodiversity, but it has proven difficult to find a satisfactory definition.

Trisomy
A trisomy is a type of polysomy in which there are three instances of a particular chromosome, instead of the normal two.
