It should be as close as possible to the likely natural gene-flow scenario: A group of <I>relatively</I> inbred mice in an established territory dominated by the urine markings of their males, invaded by an outbred male.<br /><br />Also, I emphasize <I>relatively</I> because it seems there is a range of outbreeding up to and including the point at which hybrid sterility sets in. In other words: What is he likely gene flow rate in nature?Jim Boweryhttps://www.blogger.com/profile/12686155123469135528noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-88979875578214621872009-05-23T02:18:01.703+03:002009-05-23T02:18:01.703+03:00Although the term 'hybrid vigour', or 'heterosis',...Although the term 'hybrid vigour', or 'heterosis', is usually used in relation to hybrids between two inbred lines it's presumably more widely applicable than just then. Heterozygosity implies heterosis, and so some level of hybrid vigour. This study is most likely to show the results of heterosis, nothing more complicated than that.terrythttps://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-75018609640755038512009-05-22T03:33:06.295+03:002009-05-22T03:33:06.295+03:00Fine monoracial woman and see how attractive vario...<I>Fine monoracial woman and see how attractive various types of Hispanics and Central Asians are compared to Monoracial men.

In your example, we would have to control for women's like/dislike of Hispanic or Central Asian men to isolate the effect of heterozygosity itself.<br /><br />For humans, a good study would sample from several populations, and look -in each one- whether more heterozygous/homozygous individuals differed in their attractiveness. Heterozygosity could be estimated directly from the genome, as in <A HREF="http://dienekes.blogspot.com/2009/03/decline-of-interbreeding-over-time.html" REL="nofollow">this study</A>.Dienekeshttps://www.blogger.com/profile/02082684850093948970noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-86605533432732865792009-05-22T02:40:12.124+03:002009-05-22T02:40:12.124+03:00Definition of terms:
