Genetics
animal genotyping
This is from an article describing a protocol for genotyping farm animals (based on microsatellite analysis and computer analysis if the alleles detected by PCR).
"La generazione di distanze genetiche a catena (Chord distance DAS, shared allele distance)17, tra gli allevamenti è stata determinata con l’uso del software POPULATIONS 1.2.3018. Tali distanze sono state usate per la costruzione di alberi filogenetici (neighbor-joining tree) mediante il software PHYLIP 3.519, visualizzati attraverso M-S Windows Bitmap file.bpm"

genetic distances
This can be subdivided into different categories, such as "minimum genetic distance", and others such as DAS, etc.

DAS = shared allele distances
Ds = standard genetic distance

These refer to distances on the DNA chain (hence the use of "catena".)
How far the alleles are from each other. The closer they are, the more the chances that they will not be "segregated", and that they will move together into next generation members. For example, if the gene for blue eye and small nose are very close, then one would expect the blue eye trait to appear with the small nose trait in many of the offspring members.

one reason for all members of a progeny not being identical is that the chromosomes undergo a "cross-over" as a result of which genes and alleles are scrambled. But if two genes are very close to each other, chances are they will move together, like a mother or father holding a child's hand and walking together....
