The Bulgarian Biodiversity Portal is a part of the global information exchange network established by the Convention on Biodiversity (Clearing House Mechanism - CHM). Its purpose is to offer directly or provide links to the information on biodiversity you need.
- Cell or organism that contains one set of chromosomes.
- Having the number of chromosomes present in the normal germ cell equal to half the number in the normal somatic cell.
Plants or plant parts valued for medicinal, savoury, cosmetic, or aromatic qualities.
Genetic variability among individuals within populations(population) and variability among populations.
high-input production environment
A production environment where all rate-limiting inputs to animal production can be managed to ensure high levels of survival, reproduction and output. Output and production risks(risk) are constrained primarily by managerial decisions.
Contain identical linear sequences of genes(gene) and pair during meiosis.
homozygote or homozygous
Individual having two identical copies of the same allele of a particular gene or genes at a genetic locus, and so breeding true for the corresponding characteristics.
The cultivation of ornamental and vegetable plants in gardens or smallholdings (market gardens). Latin: hortus = garden.
- An area on earth with an unusual concentration of species, many of which are often endemic to the area.
- An area of especially high pollutant concentration.
Individual organism resulting from a cross between parents of differing genotypes. Hybrids may be fertile or sterile, depending on qualitative and/or quantitative differences in the genomes(genome) of the two parents. Hybrids are most commonly formed by sexual cross-fertilization between compatible organisms, but techniques for the production of hybrids from widely differing organisms are being developed by cell fusion and tissue culture.
Region of reproduction among individuals of different species.
- Crossing of individuals from genetically different strains(strain), populations(population) or species.
- The act of crossing two different individual organisms of differing genetic constitution from different populations or different species.
- A molecular procedure in which single strands of DNA and/or RNA are mixed and subsequently bind to one another. The degree of binding is a measure of the relatedness of the strands. The procedure is used to detect RNA or DNA using suitable probes.
A state of low oxygen concentration in water and sediments, relative to the needs of most aerobic species.
