The biometrical genetics of competitive parameters in Drosophila melanogaster.

abstract：:A model involving a specific pairing of homologous double-stranded nucleic acid molecules is applied to some parts of genetic recombination. The most original features of this application of the model relate to the initiation process, a part of which can be described by a highly compact and symmetrical structure. The ...
