INTERMEDIATE PHENOTYPES. "Other qualitative characters, on the other hand, either tended towards the morphology seen in one of the parents (stamen hairs were mostly present in the intermediates, as in R. irroratum; ovary glands were consistently absent, as in R. delavayi or showed a combination of intermediate and parental characters (styles were either hairy, or glandular and hairy; and ovaries were either hairy, intermediate, or densely hairy." https://lnkd.in/dK-A3iM View in LinkedIn

STRONG PHENOTYPE DIFFERENCES. "Several characters were identified that could distinguish between the species. The quantitative characters that showed high discrimination potential ‘flowers in inflorescence’, ‘stigma width’, ‘corolla (width/length)’ and also ‘leaf (dist apex-mid/length)’, tended towards intermediate values for the hybrids. As quantitative characters are generally considered to be under polygenic control, this can be expected." https://lnkd.in/dK-A3iM View in LinkedIn

GENEROUS DELTA. "Apart from a few exceptions, the variances of repeated measurements for individuals of the same group were significantly different from each other." https://lnkd.in/dK-A3iM View in LinkedIn

TRAITS VERSUS CONSENSUS. "The morphological characters ‘stamen hairs’ and ‘style hair-coverage’ were then tested for correlation with the above calculated hybrid index." https://lnkd.in/dK-A3iM View in LinkedIn

INDEX OF HYBRIDITY. "One of the objectives of this study was to assess how the two morphological characters ‘stamen hairs’ and ‘style hair-coverage’ behave with regards to a mixed genetic background. Therefore, it was desirable to assign an index of hybridity to each intermediate individual." https://lnkd.in/dK-A3iM View in LinkedIn

UNEVEN PLANT HYBRIDIZATION. "There is strong evidence that hybridization does not occur uniformly across all plant families, and hence spontaneous hybridization seems to be more prevalent in certain families and genera. A group with high levels of natural hybridization is Rhododendron. The genus has more than 1000 species, many of which are interfertile." https://lnkd.in/dK-A3iM View in LinkedIn

TRANSGRESSIVE CHARACTERISTICS. “Studies of quantitative traits in segregating hybrid populations sometimes report the presence of phenotypes that are extreme relative to those of either parental line. The generation of these extreme phenotypes is referred to as transgressive segregation, and this is a major mechanism by which extreme or novel adaptations observed in new hybrid ecotypes or species are thought to arise.” https://lnkd.in/d4xXNs5 View in LinkedIn
