A. codominance B. polygenic inheritance C. multiple alleles D. pleiotropy E. epistasis What is the genetic condition in which the heterozygous individual has a different phenotype from the homozygous individual? What are the alleles of a gene locus when there are are more than two al...
“One of the problems with a lot of these genomics studies is that they’re very small. They don’t have enough people to really be able to identify genes in ways that are credible. This study had a hugecohortof people, so that’s really powerful,” says Monica Dus, an associate prof...
Fragment analysis is a genetic analysis method comprising a series of techniques in which DNA fragments are fluorescently labeled, separated by capillary electrophoresis (CE), and sized by comparison to an internal standard. CE-based genetic analyzers are capable ...
Genetic MarkersChromosome MappingCyclothymic DisorderSchizophreniaGene FrequencyPsychotic DisordersThe biological base of psychoses is controlled by multifactorial genotype compounds using sometimes the same gene locus or DNA information section for diverse diseases, but always in different and repeatable ...
examine mice containing missense mutations of the DISC1 gene, a locus associated with major mental illness in at least one large Scottish family. Genetic manipulation of mouse homologs of genes implicated in the etiology of psychiatric disorders is a promising avenue of research, but also one that...

The short answer is thatan allele is a variant form of a gene.Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent, namelymale parent and female parent. The copies, however, are not...
A Genome-Wide Association Study Identifies a Locus on Chromosome 14q21 as a Predictor of Leukocyte Telomere Length and as a Marker of Susceptibility for Bl... Telomeres play a critical role in maintaining genome integrity. Telomere shortening is associated with the risk of many aging-related disea...
Determination of the in vivo structural DNA loop organization in the genomic region of the rat albumin locus by means of a topological approach Nuclear DNA of metazoans is organized in supercoiled loops anchored to a proteinaceous substructure known as the nuclear matrix (NM). DNA is anchored to...
