Linkage in hexasomic inheritance

Solanums: Inheritance and Linkage Relationships

Journal 01 Heredity 1988;79:377-384; OI)~2-1503!88!$2.00 Horizontal starch gel electrophoresis was used to pertorm genetic analysis to confirm the inheritance of various isozyme loci and report on additional loci in diploid Solanum species. Aps-I, Dis-I, and Idh-1 were identified as new loci, and tetrasomic seg­ regati on was reported at the tetraploid level for Mdh-2. Of 15 loci stu died, d Is...

Uncertainty in inheritance: assessing evidence for linkage

Inheritance and linkage of isozymes in grasspea

Introduction Although isozyme markers may not be abundant in a species, their codominant inheritance has made them useful in certain situations. In linkage mapping experiments, codominant markers are often preferred over dominant markers as they carry more information on the recombination fraction than dominant markers in the F2 segregating population . An inheritance study will provide allelic...

A Genetic Study of Linkage and Inheritance in Barley

Logarithm of odds (lods) for linkage in complex inheritance.

Lod scores provide a method to unify linkage tests based on identity by descent and identity in marker state while permitting selection of the most informative individuals through their disease-related phenotypes and markers in relatives. After parametric lods are reviewed, a nonparametric approach that depends on a single logistic parameter beta is introduced. Lods for parents tested or unknow...
