Manipulation of Genes in Vitro and in Vivos. First, genetic information can be exchanged only between mem bers of the same or very closely related species. Second, these schemes depend on naturally occurring mutations or variants that may arise at very low frequencies.

Am Anfang stand ein Hausrezept,ronments or that have better fertility but are still capable of producing good yields of milk, eggs, meat, or wool. Modern methods of gene mapping, so far mostly applied in mice and man, offer new ways towards a better understanding of the genetic determination of animal performance.

,„Wir in Europa“ – Europawahlkampf 2009,e improved as a result of new methods of disease diagnosis, vaccine production, and disease prevention practices. Genetic engineering also offers the possibility of utilizing animals for the development of pharmaceutical products to benefit society. Research progress will be enhanced via manipulation of the gene pool.
