Allele age and a test for selection on rare alleles [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
An approximate expression for the probability distribution of the age of a neutral allele as a function of its frequency is derived for a population undergoing arbitrary changes in population size. A simple maximum–likelihood estimator of allele age based on frequency is also obtained.

Mapping genes through the use of linkage disequilibrium generated by genetic drift: 'Drift mapping' in small populations with no demographic expansion [PDF]

, 1998
Linkage disequilibrium has been a powerful tool in identifying rare disease alleles in human populations. To date, most research has been directed to isolated populations which have undergone a bottleneck followed by rapid exponential expansion.

DNA-based S-genotyping of Japanese plum and pluot cultivars to clarify incompatibility relationships [PDF]

, 2007
Diploid japanese plum (Prunus salicina Lindl.) cultivars are commonly self-incompatible. To date, 14 incompatibility alleles (S-alleles) have been identified and labeled with alphabetical (S-a-S-n) and 5 with numeric codes (S-1, S-3-S-6).

Genetic variability of 10 microsatellite markers in the characterization of Brazilian Nellore cattle (Bos indicus)

Genetics and Molecular Biology, 2006
We assessed the polymorphism of 10 microsatellites in Brazilian Nellore cattle (Bos indicus) using a commercial multiplex system. Allele frequencies, polymorphism information content, heterozygosity and exclusion probability were calculated.

Pleiotropy of FRIGIDA enhances the potential for multivariate adaptation. [PDF]

, 2013
An evolutionary response to selection requires genetic variation; however, even if it exists, then the genetic details of the variation can constrain adaptation.

Human Leukocyte Antigen Complex and Other Immunogenetic and Clinical Factors Influence Susceptibility or Protection to SARS-CoV-2 Infection and Severity of the Disease Course. The Sardinian Experience

Frontiers in Immunology, 2020
AimSARS-CoV-2 infection is a world-wide public health problem. Several aspects of its pathogenesis and the related clinical consequences still need elucidation. In Italy, Sardinia has had very low numbers of infections.
