How to Read a Dendogram - ZOOM VIEW
The combined distance of horizontal lines indicates
relative genetic similarity between animals
(vertical lines not included).
  • The shorter the distance, the greater the number of shared alleles
  • The longer the distance, the fewer the number of shared alleles.

Below, in the first red line, a closer looks shows the collection region (BS2), the animal number (18) being related  to BS1/41 BUT not as closely as BS2/16 (red line#3).  Where there is displayed a red and black line next to each other, the probability that the offspring was born by that broodstock is extremely high but there is also the probability that one of the broodstock further away also contributed to that offspring as well.  This can be proven out with further analysis.  You will notice each sub-group connects out to the left to larger and larger sub-groups.   As the sub-groups get larger, the quantity of alleles increases.  However, what separates one sub-group from another is the frequency of similar alleles in that particular sub-group.
