[The problem of breeding for fertility].
The reproductive success in domestic animals is an important factor towards the economical production of livestock. Thus, a lot of energy has been spent on the amelioration of the reproduction by means of genetics but no considerable success was achieved since the additive genetic variance is low. This communication is supposed to elucidate its molecular biological basis in reproduction and furthermore, the article should point out the way in research how to improve reproductive parameters. We propose to characterize all sorts of genes and their gene products that are involved in reproduction. This is to realize a full understanding of the sperm egg interaction and to derive benefit from effects like heterosis.
