The theory of gene frequencies

1976
Micro-evolution consists of change in the population either to fit it to a new place or time in a changing environment, or to improve its success in a constant environment. The modifications which take place are genetic. Sewall Wright pointed out in an article written in 1949 that ‘the elementary evolutionary process in a reasonably large homogeneous ...

Frequency Decomposition Based Gene Clustering

2015
Gene expressions have been commonly applied to understand the inherent underlying mechanism of known biological processes. Although the microarray gene expressions usually appear aperiodic, with proper signal processing techniques, its periodic components can be easily obtained.

Changing Gene Frequencies in Populations

1983
Recurrent selection populations (RSP’s) have been effectively utilized for changing gene frequencies in populations of various crop plants and for pyramiding genes for resistance to specific plant diseases. The method has been particularly adapted for cross-pollinated crops and has been especially successful in developing disease resistance in maize ...
