Genetic Architecture of Migration-Related Traits in Rainbow and Steelhead Trout, Oncorhynchus mykiss
Although migration plays a critical role in the evolution and diversification of species, relatively little is known of the genetic architecture underlying this life history in any species. Rainbow and steelhead trout (Oncorhynchus mykiss) naturally segregate for both resident and migratory life-history types, respectively, as do other members of the salmonid family of fishes. Using an experime...
متن کاملGenetic architecture of rainbow trout survival from egg to adult.
Survival from birth to a reproductive adult is a challenge that only robust individuals resistant to a variety of mortality factors will overcome. To assess whether survival traits share genetic architecture throughout the life cycle, we estimated genetic correlations for survival within fingerling stage, and across egg, fingerling and grow-out stages in farmed rainbow trout. Genetic parameters...
متن کاملStudying some reproduction characteristics of rainbow trout in Beheshtabad River of Chaharmahal and Bakhtiari Province
Rainbow trout (Oncorhynchus mykiss) is an exotic fish in the inland waters of Iran and little is known about this species in Iranian natural waters. In this study, some biological characteristics of rainbow trout such as GSI and absolute and relative fecundity were examined in 355 specimens collected monthly from Beheshtabad River of Chaharmahal and Bakhtiari Province during April 2013 to March...
متن کاملConserving Genetic Diversity in Rainbow Trout
Conserving genetic diversity is a major concern for north temperate fauna which are species poor but rich in genetic diversity. The problem is believed to be especially serious for freshwater fish where populations are isolated by barriers to migration. Isolation and low species diversity have been hypothesized to be the key ingredients in an adaptive radiation that has taken place in British C...
متن کاملcomparison of genomic evaluation methods in complex traits with different genetic architecture
the objective of this study was to compare six statistical methods for prediction of genomic breedingvalues for traits with different genetic architecture in term of gene effects distributions and number ofquantitative traits loci (qtls). a genome consisted of 500 bi-allelic single nucleotide polymorphism(snp) markers distributed over a chromosomes with 100 cm length was simulated. three differ...
