Morphological and molecular evidence reveals recent hybridization between gorilla taxa.
Molecular studies have demonstrated a deep lineage split between the two gorilla species, as well as divisions within these taxa; estimates place this divergence in the mid-Pleistocene, with gene flow continuing until approximately 80,000 years ago. Here, we present analyses of skeletal data indicating the presence of substantial recent gene flow among gorillas at all taxonomic levels: between ...
متن کاملNatural hybridization between Rhododendron delavayi and Rhododenron cyanocarpum (Ericaceae), from morphological, molecular and reproductive evidence
The natural hybridization that occurs between two sympatric species of Rhododendron subgenus Hymenanthes in Yunnan, China, was investigated. In field observations, it was noted that the putative hybrids between Rhododendron delavayi (Franch.) and Rhododendron cyanocarpum (Franch.) W.W.Smith had intermediate morphologies. On the basis of morphology, chloroplast DNA (trnL-rpl32) and nuclear DNA (...
متن کاملEfficiency of Indirect Selection to Improve Yield and Drought Tolerance in Populations Derived from Inter-Specific Hybridization of Soft Flower
The use of appropriate selection methods are important to increase yield in breeding programs. Utilization of selection indices is one of the most effective method for selection of superior genotypes to improve the complex traits such as seed yield. In order to evaluate the efficiency of different selection methods, 63 families of two F3 populations derived from inter-specific hybridization of ...
متن کاملCirsium semzinanicum (Asteraceae), a new species from Hakkâri, Turkey
Cirsium semzinanicumsp. nov. (Asteraceae) is described as a new species from Hakkâri, Turkey. The new species is a part of the sect. Epitrachys (Cardueae) and similar to Cirsium karduchorum, from which it differs in morphological characters such as leaves, involucre, phyllaries, corolla, achens and pollen morphology. Geographical distribution, habitat and IUCN conservation status of this specie...
