This study was conducted to produce a high percentage of genetically male tilapia through interspecific hybridization between Nile tilapia, Oreochromis niloticus and Blue tilapia, O. aureus and evaluate sex ratio, productive performance and heterosis of the progeny produced. The results revealed that sex ratios of the progenies of (♀ O. aureus x ♂ O. niloticus) and (♀ O. niloticus x ♂ O. aureus...

This article focuses on the 2D hybrid technique between the Frequency Domain Transmission Line Matrix Method (FDTLM) and the Wave Concept Iterative Procedure (WCIP). 3D hybridization has already been studied, but results may be improved through a better knowledge of method order. Consequently, developing 2D hybridization aims at understanding the hybridization in simplest problems, especially b...

Contemporary evolution through human-induced hybridization occurs throughout the taxonomic range. Formerly allopatric species appear especially susceptible to hybridization. Consequently, hybridization is expected to be more common in regions with recent sympatry owing to human activity than in areas of historical range overlap. Coyotes (Canis latrans) and gray wolves (C. lupus) are historicall...

Of all of the challenges which face the selection of relevant features for predictive data mining or pattern recognition modeling, the adaptation of computational intelligence techniques to feature selection problem requirements is one of the primary impediments. A new improved metaheuristic based on Greedy Randomized Adaptive Search Procedure (GRASP) is proposed for the problem of Feature Sele...

The electrical and optical properties of flat planar buckled siligraphene (SiC) monolayer are examined using a first principles approach. Buckling between the Si C atoms in SiC structures influences impacts 2D nanomaterial, according to our results. electron density is calculated, as well effects buckling on it. According findings, semiconductor nanomaterial with direct electronic band gap that...

The role of hybridization in evolution has been debated for over a century. Recent molecular genetic studies indicate that hybridization is surprisingly frequent in natural populations, and that it may allow populations to regain traits that have been lost and possibly to replace damaged alleles with functional copies from related species.
