We also assume semelparous individuals living in a population of infinite size. The events of the lifecycle occur ...

Dominant alleles cannot be carried along in a hidden state like this, and if a dominant allele is present it is expressed. Dominant alleles, if present, sh ...

The stable inheritance of 3D chromosome pairs from the BC2F2 to BC2F5 generations of (Ae. tauschii × S. cereale) × triticale hybrids can be considered as a successful attempt of D-genome introgression into triticale, without using deletion or mutation lines of wheat or triticale with lack of the who ...

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.
