Discussion

In this study we linked previous approaches that infer paternity with sibships or paternity with population parameters to jointly infer paternity, sibships and the pollen dispersal kernel in a hybrid zone of Antirrhinum majus. We find that dispersal is leptokurtic, with half of seeds being sired by pollen donors within 40m of the maternal plant, and remaining donors being spread up to more than 2km away. Using the dispersal kernel as a null distribution, we find than maternal plants towards the edges of the hybrid zone are more likely to receive pollen from the local parental subspecies than would be expected by chance. Below we discuss these findings and how they relate to maintenance of the hybrid zone.
This is notes from here on.

Male fitness as a mechanism of HZ maintenance

Parental genotypes have higher male fitness on their own side.
Matches Dave's pedigree.

Biological relevance of dispersal shape/distance

If theres selection through male fitness, dispersal is somehow bounded, but that's beyond this paper. You'd need to fit an interaction term or something.

Could incorrect assignment affect results?
