Environment-Dependent Genotype-Phenotype Associations in Avian Breeding Time

Environment-Dependent Genotype-Phenotype Associations in Avian Breeding Time

Understanding how genes shape phenotypes is essential to assess the evolutionary potential of a trait. Identifying the genes underlying quantitative behavioral or life-history traits has, however, proven to be a major challenge. The majority of these traits are phenotypically plastic and different parts of the genome can be involved in shaping the trait under different environmental conditions....

Replicating genotype–phenotype associations

NCI-NHGRI Working Group on Replication in Association Studies The study of human genetics has recently undergone a dramatic transition with the com­ pletion of both the sequencing of the human genome and the mapping of human haplo­ types of the most common form of genetic variation, the single nucleotide polymorphism (SNP). In concert with this rapid expansion of detailed genomic information, c...

Finding Genotype and Phenotype Associations

Genotype-Phenotype Associations in a Nonmodel Prokaryote

UNLABELLED To help define the biological functions of nonessential genes of Francisella novicida, we measured the growth of arrayed members of a comprehensive transposon mutant library under a variety of nutrition and stress conditions. Mutant phenotypes were identified for 37% of the genes, corresponding to ten carbon source utilization pathways, nine amino acid- and nucleotide-biosynthetic pa...

Genotype-phenotype associations in obesity dependent on definition of the obesity phenotype.

OBJECTIVE In previous studies of associations of variants in the genes UCP2, UCP3, PPARG2, CART, GRL, MC4R, MKKS, SHP, GHRL, and MCHR1 with obesity, we have used a case-control approach with cases defined by a threshold for BMI. In the present study, we assess the association of seven abdominal, peripheral, and overall obesity phenotypes, which were analyzed quantitatively, and thirteen candida...
