Therefore, it is important to understand the genetic structures of animal populations to be able to protect the genotypic structure of the races that face the danger of becoming extinct.
After assigning each sampled individual to a genotype, we calculated measures of genotypic structure for each plot separately, including richness, evenness and Shannon's Diversity (Arnaud-Haond et al.
Thus, our rarefaction analysis revealed that relatively few samples could be taken from a 1 x 1 m plot to accurately reflect fine-scale genotypic structure.
The effect of asexual reproduction and intergenotypic aggression on the genotypic structure of the sea anemone Actinia tenebrosa.
Temporal genetic changes are further evidenced in the multilocus genotypic structure, as summarized by frequencies of parental, F.
For example, year-to-year changes in genotypic structure within--and variance among--populations may result from differences in relative recruitment from immigrant versus resident individuals (Charlesworth and Geisei 1972; Long 1986).
nm] would be that microgeographic genotypic structure is evident within marshes, on a finer scale than anticipated given the degree of movements by adult males and females among marshes.
simulated sympatric) populations to better understand the mechanisms behind changes in genotypic structure within the hybrid zone formed by G.
Six replicates of the "mixed" treatment that were not used in demographic analyses were followed concurrently to document differences in genotypic structure over time (Scribner, 1992; Scribner and Avise, submitted).
Both of the alleles (C and G) of the UoG-CAST polymorphism and three genotypic structures (CC, CG, GG) were found in the CAST locus in TGC (Fig.
