title: Mendelian inheritance, linkage and genotypic  disequilibrium in microsatellite loci isolated from Hymenaea courbaril (Leguminosae).
abstract: The Neotropical tree Hymenaea courbaril,  locally known as Jatobá, is a valuable source of lumber and also produces comestible  and medicinal fruit. We characterized Mendelian inheritance, linkage and  genotypic disequilibrium at nine microsatellite loci isolated from H.  courbaril, in order to determine if they would provide accurate estimates  of population genetic parameters of this important Amazon species. The study  was made on 250 open-pollinated offspring originated from 14 seed trees. Only  one of nine loci presented significant deviation from the expected Mendelian  segregation (1:1). Genotypic disequilibrium between pairwise loci was  investigated based on samples from 55 adult and 56 juvenile trees. No genetic  linkage between any paired loci was observed. After Bonferroni's corrections  for multiple tests, we found no evidence of genotypic disequilibrium between  pairs of loci. We conclude that this set of loci can be used for genetic diversity/  structure, mating system, gene flow, and parentage analyses in H. courbaril populations.
