We then discuss the technical and conceptual complexities associated with crossing experiments and behavioural observations designed to reveal reproductive incompatibility.
On the basis of morphological features, crossing experiments, and seed protein electrophoretic profiles, Krapovickas and Gregory classified cultivated peanut into two subspecies (subsp. hypogaea and subsp. fastigiata) and six botanical varieties, which include var.
The culture method and crossing experiments were described previously [24], [25].
Commonly, traits controlled by single, major Mendelian genes are isolated using genetic linkage maps created from crossing experiments.
Therefore, crossing experiments involving both intra- and inter-population matings is a possible approach to test whether sexually antagonistic coevolution acts within populations [e.g. 8], [11], [32] [35].
As we first discovered sexual strains of U. linza in this study, crossing experiments could be carried out between U. linza and U. prolifera.
Notably, crossing experiments reveal no detectable intrinsic postzygotic reproductive isolation between M and S in F1 or backcross individuals raised in the laboratory [21].
Further, crossing experiments suggest that bidirectional CI is a major isolation factor between some strains and closely related species [4], [5], [17], [23] [25].
carrying the MAT1-1 and MAT1-2 locus respectively, were subjected to pairwise crossing experiments on plates under daylight conditions (indicated by arrows on Fig. 4).
Our evidence based on the analysis of selfed lines and crossing experiments unequivocally supported the hypothesis that obligate parthenogenesis in Brachionus calyciflorus is inherited in a Mendelian fashion.
We analyzed the results of crossing experiments as follows.
