Is there a relationship between multilocus homozygosity and dominance rank in sea anemones? A reply to Zeh and Zeh
Article Abstract:
Linear regression analysis has been used to show the statistical association of the dominance rank with homozygosity at 11 allozyme loci used to distinguish seven clones in a study of the sea anemone Anthopleura elegantissima. The association is explained by a homozygote agressive superiority hypothesis. However, such an association can not be expected since it is unlikely that homozygosities at allozyme loci will be substantially correlate with those at other loci. Furthermore, evidence has shown serious problems in the statistical analysis of links between multilocus heterozygosity and characteristics such as dominance rank.

Aggression, habituation, and clonal coexistence in the sea anemone Anthropleura Elegantissima
Article Abstract:
Results of intraspecific competition for space among A. elegantissima clones is possibly decided by a combination of inherent behavioral and morphological attributes of competing clones and previous histories of interactions with other clones. As clones vary widely in their fighting abilities, clonal coexistence in A. elegantissima probably includes an interaction among the complexities of agonistic behavior, a scope for colonization, and trade-offs between aggression and sexual reproduction. A study confirms that occurring clones often differ in many traits.

Homozygosity, self-recognition, and aggressive ability in the sea anemone, Anthopleura elegantissima
Article Abstract:
The sea anemone Anthopleura elegantissima is examined with regards to its homozygosity, self-recognition and aggressive ability. A high correlation between homozygosity and dominance rank is observed. Evidence also supports the theory that numerous loci contribute in an additive manner to allorecognition. A multilocus recognition system could also shed light on why the A versus E and D versus G clone pairs respond nonaggressively to each other.
