Description:
The life cycles of sexually reproducing animals and flowering plants begin with male and female gametes and their fusion to form a zygote. Selection at this earliest stage is crucial for offspring quality and raises similar evolutionary issues, yet zoology and botany use dissimilar approaches. There are striking parallels in the role of prezygotic competition for sexual selection on males, cryptic female choice, sexual conflict, and against selfish genetic elements and genetic incompatibility. In both groups, understanding the evolution of sex-specific and reproductive traits will require an appreciation of the effects of prezygotic competition on fitness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bernasconi, G -- Ashman, T-L -- Birkhead, T R -- Bishop, J D D -- Grossniklaus, U -- Kubli, E -- Marshall, D L -- Schmid, B -- Skogsmyr, I -- Snook, R R -- Taylor, D -- Till-Bottraud, I -- Ward, P I -- Zeh, D W -- Hellriegel, B -- New York, N.Y. -- Science. 2004 Feb 13;303(5660):971-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Environmental Sciences, University of Zurich, Winterthurerstrasse 190, CH-8057 Zurich, Switzerland. bernasco@uwinst.unizh.ch〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14963320" target="_blank"〉PubMed〈/a〉
