The aim of this study was to determine the haplotype groups and identify the specific alleles associated with desirable agronomic characteristics in bread wheat. For this purpose, 42 local bread wheat genotypes belong to Iran region and nine commercial cultivars along with Chinese Spring variety (reference genotype) were cultivated in the format of augmented design and evaluated based on their ...
Biophysical constraints determine the selection of phenotypic fluctuations during directed evolution
Phenotypes of individuals in a population of organisms are not fixed. Phenotypic fluctuations, which describe temporal variation of the phenotype of an individual or individual-to-individual variation across a population, are present in populations from microbes to higher animals. Phenotypic fluctuations can provide a basis for adaptation and be the target of selection. Here we present a theore...
Hyperplasia and hypertrophy, or their counterparts hypoplasia hypotrophy, are elements of the adjustment organ size function in animals according to needs under altered environmental conditions. As such processes costly terms energy biomaterials, it is assumed that they beneficial for survival individual. The ability perform adjustments limitations scope considered be adaptive genetic traits wh...
Present methods for genetic evaluation of livestock are largely based on phenotypic information and pedigree registration. Genomics offers the opportunity to dissect phenotypic differences at the molecular level, which provides a better insight into the underlying genetic model. This affects genetic evaluations as well as selection strategies. Opportunities to utilize molecular and phenotypic i...
There is increasing interest in understanding the processes that maintain phenotypic variation in groups, populations, or communities. Recent studies have investigated how the phenotypic composition of groups or aggregations (e.g., its average phenotype or phenotypic variance) affects ecological and social processes, and how multi-level selection can drive phenotypic covariance among interactin...
