The estimation of linkage from the offspring of selfed heterozygotes

摘要: Five methods of solution are given the statistical problem presented by typical linkage data. The example chosen shows various errors into which use inefficient statistics leads. Of efficient method maximum likelihood possesses advantage that it may be applied directly to any analogous problem, and is related in a previously unsuspected way measure discrepancyX 2. product ratio method, for using table provided, enjoys practical advantages other solutions, addition unaffected differential viability, if this caused one factor only. minimumX 2, unlike two, laborious computation, seems possess no special theoretical interest.
