Background Ghezel sheep are highly prolific and one of the local sheep breeds in Iran and Turkey. Growth differentiation factor-9 (GDF9) gene has been found to be essential for growth and differentiation of early ovarian follicles. Novel mutations in GDF9 have been associated with increased ovulation rates and high litter sizes in heterozygous carriers. Therefore, fecundity gene for GDF9 (FecGH...

Objective: This study aims to investigate the model of the relationship between differentiation and moral justice in sexual satisfaction. Methods: This descriptive and applied research was done based on structural equations. The statistical population consisted of 300 individuals who were selected via the convenience sampling method. The participants completed the Skowron (1995) differentiati...

Predicting Adolescents’ Self-Differentiation and Attachment Styles Based on Family Flexibility, Parents’ Level of Self-Differentiation and Parental Attachment Styles F. Asl Dehghan, M.A. H. Rezaian, Ph.D. S. Hosseinian, Ph.D. The main purpose of the present study was to determine the role of family flexibility, parents’ level of self-differentiation, and pa...

The purpose of this study was to determine "The Effect Product Differentiation and Brand Image on repurchase interest Scarlett Whitening Products (Case Study Body Lotion in the People Pulau Rakyat Asahan District)". two variables, where variable is measured by a Likert scale. population were 366 people who female with sample 191 respondents taken from part existing population. And using Slovin ...

The extent of divergence between partially isolated sub-populations for electrophoretically detectable alleles was formulated assuming the island model of migration and the charge state model of mutation. At equilibrium the ratio of the variance of charge between the means of k different islands to the average within-island variance of charge was shown to be approximately 4Nemk2/(k-1)2 where Ne...

We introduce and analyze several aspects of a new model for cell differentiation. It assumes that differentiation of progenitor cells is a continuous process. From the mathematical point of view, it is based on partial differential equations of transport type. Specifically, it consists of a structured population equation with a nonlinear feedback loop. This models the signaling process due to c...

Despite recent advances in population genetic theory and empirical research, the extent of genetic differentiation among natural populations of animals remains difficult to predict. We reviewed studies of geographic variation in mitochondrial DNA in seabirds to test the importance of various factors in generating population genetic and phylogeographic structure. The extent of population genetic...

Domestication and selection are processes that conserve the pattern of genetic diversities between and within populations. Identification of genomic regions that are targets of selection for phenotypic traits is one of the main aims of research in animal genetics. An approach for identifying divergently selected regions of the genome is to compare FST values among loci to estimate the genetic v...
