An EM algorithm for mapping quantitative resistance loci

Article Abstract:

A maximum likelihood method to map the quantitative resistance loci (QRL) is developed and implemented via a multicycle expectation-conditional-maximation (ECM) algorithm under the threshold model. The result showed that it estimates both the QRL effects and the thresholds that link the disease liability and the categorical phenotype.

Mapping quantitative trait loci underlying triploid endosperm traits

Article Abstract:

Research has been conducted on endosperm quantitative trait loci genotypes. The authors describe their study of these genotypes' conditional probabilities, and report that the use of the probabilities has helped them to develop a multiple linear regression method which provide accurate estimates of the quantitative trait loci effect.

Multivariate segregation analysis for quantitative traits in line crosses

Article Abstract:

A multivariate segregation analysis (MSA) that takes advantage of the correlation structure of multiple quantitative traits to detect major genes is proposed.
