00:00:00 +0000https://www.bunkerlinge.org/en/lexicon/basics/linkage-drag/Moving a single gene from an outside line into a variety always brings a piece of chromosome with it, and how large that piece stays is decided not by the number of crosses but by the position in the genome.https://www.bunkerlinge.org/en/lexicon/basics/sex-reversion/Sun, 16 Aug 2026 00:00:00 +0000https://www.bunkerlinge.org/en/lexicon/basics/sex-reversion/In sex reversion a genetically female plant forms fertile male flowers, or a male plant fertile female ones, triggered through the ethylene pathway, and both feminised seed and selfing rest on it.https://www.bunkerlinge.org/en/lexicon/basics/single-seed-descent/Sun, 16 Aug 2026 00:00:00 +0000https://www.bunkerlinge.org/en/lexicon/basics/single-seed-descent/In single seed descent exactly one seed from each plant carries the next generation, and in cannabis the method reaches functionally true-breeding lines in about six rounds.https://www.bunkerlinge.org/en/lexicon/basics/heterozygosity/Sat, 15 Aug 2026 00:00:00 +0000https://www.bunkerlinge.org/en/lexicon/basics/heterozygosity/Heterozygosity means a plant carries two different variants at one place in its genome, and in cannabis that is the normal state rather than the exception.https://www.bunkerlinge.org/en/lexicon/basics/homozygosity/Sat, 15 Aug 2026 00:00:00 +0000https://www.bunkerlinge.org/en/lexicon/basics/homozygosity/Homozygosity means a

progeny.https://www.bunkerlinge.org/en/lexicon/basics/recombination/Sat, 15 Aug 2026 00:00:00 +0000https://www.bunkerlinge.org/en/lexicon/basics/recombination/Recombination is the rearrangement of alleles during the formation of gametes, and in some stretches of the genome it happens so rarely that linked traits stay together.https://www.bunkerlinge.org/en/lexicon/basics/transgression/Sat, 15 Aug 2026 00:00:00 +0000https://www.bunkerlinge.org/en/lexicon/basics/transgression/Transgression describes offspring whose trait values fall outside the range of both parents, and in the case measured it arose from similar parents rather than distant ones.
