Båda könen hade en positiv Batemangradient, men att honornas var högre. De två ovanstående begreppen används ofta för att beskriva olika arters sociala system kring fortplantning. I also show that genetic incompatibilities can evolve rapidly despite low genome-wide levels of divergence but that divergence in regulatory regions and proteins potentially allows fast evolution of molecular mechanisms impairing or preventing costly heterospecific fertilization. English We do not consider it necessary to create a legal basis for call-by-call selection. Ecology letters, 15 11

Sex, Sperm and Speciation: On sexual selection and fertility in hybridizing flycatchers

Finally, by exploring the testes transcriptomes and sperm proteomes of both species, I highlight the importance of gene and protein regulation mechanisms in facilitating phenotypic divergence between these species paper V. Det är inte en modell av data från en viss population, utan en modell av ett förenklat idealiserat system. When hybridization is maladaptive, species-specific mate preferences are selectively favored, but low mate availability may constrain species-assortative pairing. SV val urval sortiment axplock urplock selektion. Gradient betyder helt enkelt lutning — hur mycket den reproduktiva framfången ökar, i medeltal, per extra partner. I nästa val till Europaparlamentet kommer medborgarna att kunna välja bland ett brett sortiment av politiska familjer för att framföra vilken sorts Europa de vill ha.
