Different lineages experience different rates of phenotypic diversification, resulting in greater or lower variance in the expression of phenotypic traits among the species within a lineage. Here, morphological diversification is investigated in 14 different trematode families, based on a dataset comprising morphometric data on body size and 4 anatomical structures (oral sucker, ventral sucker,...

Determining which underlying traits contribute to differences in whole-animal performance can be difficult when many traits differ between individuals with high and low capacities. We have previously found that migratory (anadromous marine) and non-migratory (stream-resident) threespine stickleback (Gasterosteus aculeatus) populations have genetically based differences in prolonged swimming per...

in order to investigation of morphological traits, yield and its components in three cultivars of grain sorghum (kimia, sepideh, payam) and two promising lines (m5, m2) under four density (240000, 205000, 170000 and 135000 plant/m2), experiment was conducted as factorial design based on randomized complete block design with three replications in birjand agricultural research station, during 200...

Monogenic inheritance and linkage among four morphological traits of lentil were established on the basis of F1 observations and analysis of 204 F2 plants in a cross for development of pubescence on peduncle, 228 F2 plants in a cross for tendril formation, 574 F2 plants in 5 crosses for flower numbers per peduncle and 464 F2 plants in 4 crosses for flower color under field conditions. Developme...

To evaluate the effect of ascorbate and gibberellin on some morphological traits and relative water content of medicinal plant fenugreek in different levels of salinity, an experiment was carried out in Shahr- e - Rey branch of Islamic Azad University in October 2012. The experiment was arranged as factorial experiment in the basis of completely randomized design with four replications. The exp...

Inter and intra-population variation in morphological traits, such as body size and shape, provides important insights into the ecological importance of individual natural populations. The radiation of Diaptomid species (~400 species) has apparently produced little morphological differentiation other than those in secondary sexual characteristics, suggesting sexual, rather than ecological, sele...

genetic diversity is one of principle factors to succeed in breeding programs, so its determination is vital in the using of plant genetic resources. with the aim of evaluation of genetic diversity among safflower landraces, 20 lines (14 iranian and 6 foreign lines) were studied for phenotypic and genotypic variations using agro-morphological traits and rapd markers. field study was conducted i...
