Allelic relationships and inheritance of brown midrib trait in Sorghum

Article Abstract:

An analysis of seven brown midrib mutants of sorghum, which occur naturally or through induced mutations, reveals a partial control of the brown midrib traits by specific genes in the nuclear genome of sorghum. Four naturally occurring mutants exhibit allelism among themselves and with the induced mutation bmr-6. There is no allelic relationship between these five alleles and induced mutations bmr-12 and bmr-18. Certain modifying genes have the capacity to alter the brown midrib trait expression.

A comparison of rarefaction and Bayesian methods for predicting the allelic richness of future samples on the basis of currently available samples

Article Abstract:

A study was conducted using extensive simulations to compare the performance of Monte Carlo rarefaction (repeated random sampling) method with a simple Bayesian approach, which was developed based on the Ewens sampling distribution. It was found that neither the Bayesian method nor the Monte Carlo rarefaction method performed uniformly better than the other.
