Selection effects on diversity and genetic gain. [PDF]

open access: yesSilva Fennica, 1991
Four different methods of truncation selection were studied in a population consisting of a large number of unrelated full sib families of equal size: phenotype selection, family selection, within-family selection and combined index selection (optimal ...

The Symmetry of the Genetic Code and a Universal Trend of Amino Acid Gain and Loss [PDF]

open access: greenarXiv, 2007
Part 1 of the study intends to show that the universal trend of amino acid gain and loss discovered by Jordan et al. (2005) can be accounted for by the spontaneity of DNA typical damages. These damages lead to replacements of guanine and cytosine by thymine.

Visualizing genetic constraints [PDF]

open access: yesAnnals of Applied Statistics 2013, Vol. 7, No. 2, 860-882, 2013
Principal Components Analysis (PCA) is a common way to study the sources of variation in a high-dimensional data set. Typically, the leading principal components are used to understand the variation in the data or to reduce the dimension of the data for subsequent analysis. The remaining principal components are ignored since they explain little of the

Genomic selection in United States dairy cattle

open access: yesFrontiers in Genetics, 2022
The genomic selection program for dairy cattle in the United States has doubled the rate of genetic gain. Since 2010, the average annual increase in net merit has been $85 compared to $40 during the previous 5 years.
