Intraspecific Genetic Variation of Five Wild Indonesian Striped Snakehead (Channa striata (Bloch, 1793)) Populations Assessed Through 16S rRNA Sequences [PDF]
, 2023 The striped snakehead (Channa striata) belongs to the order Perciformes, suborder Channoidei, and the family Channidae. This fish is native to Sumatra, Java, and Kalimantan, but introduced to Sulawesi and Papua.

Evolution in the genus Arum: a comparative analysis of morpohological and genetic variation. [PDF]
Testing the correlation of morphological and genetic marker variation enables the investigation of evolutionary processes. Knowledge of evolutionary processes can be used to identify those morphological characters that could be used to produce ...

Genetic variation in the zebrafish [PDF]
Genome Research, 2006 Although zebrafish was introduced as a laboratory model organism several decades ago and now serves as a primary model for developmental biology, there is only limited data on its genetic variation. An establishment of a dense polymorphism map becomes a requirement for effective linkage analysis and cloning approaches in zebrafish. By comparing ESTs to

Genetic analysis of environmental variation [PDF]
, 2010 Environmental variation (V-E) in a quantitative trait - variation in phenotype that cannot be explained by genetic variation or identifiable genetic differences - can be regarded as being under some degree of genetic control. Such variation may be either

Genetic study of litter size and litter uniformity in Landrace pigs
Revista Brasileira de Zootecnia, 2020 We aimed to estimate litter size and litter uniformity genetic parameters and genetic trends of Landrace pigs at birth and at three weeks by using multitrait analyses for 2,787 litters.

Polymorphism of the grasshopper Rhammatocerus schistocercoides populations revealed by RAPD [PDF]
Pesquisa Agropecuária Brasileira, 2002 The objective of this work was to study the genetic variability of the grasshopper Rhammatocerus schistocercoides (Orthoptera: Acrididae) using RAPD analysis among individuals from three populations, one from Colombia and two from Brazil (Goiás and Mato ...

Cryptic genetic variation [PDF]
Current Biology, 2008 What is cryptic genetic variation? Cryptic genetic variation refers to unexpressed, bottled-up genetic potential. It is not normally seen, but is expressed under abnormal conditions such as in a new environment or a different genetic background.

Variations of Genetic Algorithms
CoRR, 2019 The goal of this project is to develop the Genetic Algorithms (GA) for solving the Schaffer F6 function in fewer than 4000 function evaluations on a total of 30 runs. Four types of Genetic Algorithms (GA) are presented - Generational GA (GGA), Steady-State (mu+1)-GA (SSGA), Steady-Generational (mu,mu)-GA (SGGA), and (mu+mu)-GA.

Spatially structured genetic variation in a broadcast spawning bivalve: quantitative vs. molecular traits [PDF]
, 2003 Understanding the origin, maintenance and significance of phenotypic variation is one of the central issues in evolutionary biology. An ongoing discussion focuses on the relative roles of isolation and selection as being at the heart of genetically based
