Previous studies on sichel reported a variation coefficient greater than 10% for head height (4), preorbital distance (5), eye diameter (6), postorbital distance (7), length of base D (13), and distance P-v (19) (Raczynski et al., 2011), but the specimens from this study belong to the population which could affect intrapopulation
Genetic variability with in populations: Genetic diversity analysis indicated that all populations were similar with respect to intrapopulation
level of genetic variations.
In an attempt to overcome this obstacle, the State University of Northern Rio de Janeiro (UENF) started in 1998 the passion-fruit breeding program via intrapopulation
recurrent selection aiming at the release of more-productive cultivars adapted to the climatic conditions of the Norte Fluminense region and other producing regions in Brazil (VIANA et al., 2004).
This species has genetically determined intrapopulation
polymorphism in spine color, varying from white to purple to green (Wise, 2011).
variation in thermal reaction norms for growth rate: Evolution of latitudinal compensation in ectotherms with a genetic constraint.
Although most previous studies explain how the density dependence process occurs at the intrapopulation
level, some ecologists argue that organizational interdependence can exist at multiple levels of analysis (Carroll & Wade, 1991).
The analysis of molecular variance (AMOVA) indicated that 31.79% of the total variance is between populations and 68.21% within populations, demonstrating that the higher genetic differentiation is at intrapopulation
component than at interpopulation component (Table 5).
According to Hardy-Weinberg, and to the fixation index (f), the intrapopulation
genetic variability has been quantified through the number of alleles per locus (A), the percentage of polymorphic loci (P) and the observed (Ho) and expected (He) heterozygosity (Ho) (Hamrick, 1983).
MaF36 displayed the highest level of intrapopulation
variation in terms of expected heterozygosity while BM8125 was slightly less variable than the other studied loci.
chrysippus, we found very minor variation which may be intrapopulation
variation in D.
