The effect of mixed selected and unselected samples on the power of QTL mapping

Article Abstract:

The effects of within-sample selection to detect linkage with quantitative trait loci (QTL) have been examined by Mackinnon and Georges. The effects of mixed selected and unselected samples are now examined and it is shown that even small proportions of the sample originate from an unselected population, although the loss of power is effectively neutralized. Also the power to determine QTL may rise if the selection intensity in selected subpopulations is high.

Inheritance of a white flower mutant in kenaf

Article Abstract:

A mutant kenaf, Hibiscus cannabinus, with white flowers was crossed with two cultivars with yellow flowers to determine the mode of inheritance of the mutant flower color. Segregation analysis in the second filial generation and backcross studies reveal that the white flower color trait is under the control of a single recessive allele designated as wf. These findings have important implications in linkage studies of these plants.
