Document Summary
Seeks to control a territory to attract and mate with females. Morphotype and male matting strategy are linked and genetically determined. The satellite allele is dominant to the independent allele. In females, there is no evident phenotypic difference between the two alleles. Around in 2006, a third male mating type/strategy: no ornament and appear same as female. Sneak onto leks unnoticed by other males and mate with females while territorial males are distracted. Genotype is part of the same supergene that controls the other two mating types: faeder allele is dominant to both territorial and satellite alleles. Genetic locus relevant for the mating strategy is located on an autosome or non-sex chromosome. July 3: males 84% territorial, 14% satellite, 1% faeder, females 99% normal, 1% diminutive. Stable frequencies in captive and wild populations. Lek size: residences have higher copulation success with more lek size, lek size (land size) doesn"t matter much in satellite.
