... HPLC analysis revealed that yellow Gower Ramsey accumulates violaxathin, 9-cisviolaxathin and neoxanthin, orange Sunkist accumulates an additional β-carotene, and White Jade is devoid of carotenoid compounds. Molecular characterization indicated that the three Oncidium cultivars exhibited varied ex ...

By isolating and culturing the ascospores in the linear order in which they are found in the organism, he discovered the patterns of first- and second-division segregations (4:4 and 2:2:2:2, respectively). These patterns result from crossing over, or the lack of it, between the trait being ...

Genetic mapping of mutations using phenotypic pools and

... In the pooling approach to linkage analysis (bulk segregant analysis, ref. 1-4), individuals of a segregating population are sorted into two categories, or pools, based on either genotype or phenotype. In the simplest case of phenotypic pooling the phenotype is controlled by a single genetic locus. ...

Quantitative trait locus

A quantitative trait locus (QTL) is a section of DNA (the locus) that correlates with variation in a phenotype (the quantitative trait). The QTL typically is linked to, or contains, the genes that control that phenotype. QTLs are mapped by identifying which molecular markers (such as SNPs or AFLPs) correlate with an observed trait. This is often an early step in identifying and sequencing the actual genes that cause the trait variation.Quantitative traits are phenotypes (characteristics) that vary in degree and can be attributed to polygenic effects, i.e., the product of two or more genes, and their environment.
