Current methods for mapping imprinted quantitative trait locus iQTL with inbred line crosses assume fixed QTL effects. When an iQTL segregates in experimental line crosses, combining different line crosses with similar genetic background can improve the accuracy of iQTLs inference. In this article, we develop a general interval-based statistical variance components framework to map iQTLs underl...

Patterns of inheritance of the chloroplast genome in Passiflora were analyzed by examining the progeny from both interspecific and intraspecific crosses. Artificial crosses of field-collected material were performed in greenhouses at The University of Texas at Austin. DNA from fresh leaf material was analyzed by Southern blot techniques to identify the donor of the chloroplast genome. Initially...

Genetic crosses between mutants defective in the known pre-early genes of T5 and BF23 and the detection of putative N-terminal fragments have allowed the determination of the order of genes along the initially transferred 8% section of DNA of these phages.

The F1 along with parents of a 4 x 6 line x tester crosses in safflower were studied and seven parameters, i.e., D 2 7 based on 7 characters and D24 based on yield and its 3 direct componenets and mid parent value (MP-Y), F1 mean (F1-Y), relative heterosis (RH-Y), biparental average GCA (MPGCA-Y) and SCA effect (SCA-Y) for yield were estimated. Twenty four selected crosses were studied for segr...
