n.(used with a sing. v.) 1.the branch of biology that deals with the principles and mechanisms of heredity and with the genetic contribution to similarities and differences among related organisms. 2.the genetic properties or constitution of an organism or group. ...
Gene resource plays an important role in genetics and breeding.Mining useful alleles is one of the main activities in plant breeding.With the advances of genomics and sequencing technologies,many QTL for important traits have been isolated and characterized,at which a large amount of unexploited alle...
The previously reported association between dopamine D4 receptor alleles and novelty seeking was not replicated. Possible reasons for this include differences in personality inventories, ethnicity, and type I or type II errors. 展开 关键词: path analysis structural equation modelling multiple regression ...
In a large plant natural population, GWAS was a powerful method for identifying QTLs with multiple alleles at the whole-genome level based on linkage disequilibrium (LD)11,12. In a recent study, a GWAS was performed with 129 peach accessions to identify QTLs controlling 12 key agronomic traits...
F, and recombinant inbred lines (RILs, F6:8) populations derived from an upland cotton ( and RILs were constructed, containing 155 and 190 loci and with a total map distance of 959.4 centimorgans (cM) and 700.9cM, respectively. We screened fiber quality QTL across multiple generations and en...
By combining behavioral experiments with crosses designed to introgress alleles from the asexual into the sexual genome, we found that sexual attractiveness, mating, egg fertilization and plastic adjustment of offspring sex ratio (in response to variation in local mate competition) are decayed in ...
We calculated a population-level index of dopamine functioning using 9 commonly investigated genetic polymorphisms encoding dopamine transporters and receptors, derived from a meta-analysis with data from 805 independent samples involving 127,685 participants across 73 societies or territories. We found ...
One was directional and independent level selection according to the breading aim for the canonicalcharacters with higher heritability. Another was to keep the genetic di-vergence in the different population of families. It was shown by usingactual case analysis that the former selection was a ...
