Relationship Matrix to Compute

Use this feature to specify the relationship metric you want to compute across all marker variables .

Select:	When you want to:
Identity By Descent	Compute an estimate of the probability that two individuals share an allele that came from the same ancestor at a locus .
Identity By State	C ompute the probability of two individuals sharing the same copy of an allele (not necessarily inherited from the same ancestor). This procedure uses the SAS Distance Procedure with Gower's Similarity Metric and a Range standardization (mean IBS across all markers) . Note : If Identity By State is chosen, all SNPs must be polymorphic in order to avoid errors in the Distance Procedure as the Range at monomorphic loci is 0 and standardization cannot be done.
Allele Sharing Similarity	C ompute the probability of two individuals sharing the same copy of an allele (not necessarily inherited from the same ancestor). This procedure uses the SAS Distance Procedure with Gower's Similarity Metric but without the Range Standardization.
