T.F. Cross et al.
Mass spawning where several females and males are placed in a tank and allowed
to spawn randomly (opposite to single pair mating)
Marker assisted selection using molecular markers to enhance traditional breeding programmes
MHC major histocompatibility complex; immune-response genes
Microarray plate with sequences of large numbers of functional genes applied, so
that the level of activity of each can be assessed
Microsatellite loci tandemly arrayed DNA repeats of two or more nucleotides as
used in human forensics
Mitochondria organelles in each cell with haploid genomes
Natal homing returning to the area of birth to reproduce (=philopatry)
Neutral loci loci unaffected by natural selection
Outbreeding reduction of fitness due to crossing of distinct populations or species,
due to break down of co-adapted genes complexes
Progenitor population ancestral population
Quantitative trait factor such as growth rate which is normally-distributed
amongst individuals of a population
Sex ratio number of females relative to males
Sire male parent
Stock fisheries term for a management unit, which may be a genetic population
Subtractive hybridisation technique to concentrate on genes with different levels
of activity in microarrays
Transgenic GM organism where there has been the introduction of a gene from
another species
Translocated movement of species or population outside its native area
Triploid organism with three sets of chromosomes instead of the normal two, usually with two female sets
VNTR variable number tandem repeat, microsatellite and minisatellite DNA
sequences
