Abstract:
The phylogenetic relationships of the genus Atractylodes DC. was analyzed using the nuclear ribosomal ITS and three chloroplast fragments, including atpB-rbcL, psbB-psbF and trnL-trnF intergenic spacer (IGS) sequences. Phylogenetic analyses revealed that A. lancea subsp. luotianensis and A. lancea, A. chinensis var. liaotungensis and A. coreana form monophyletic terminal clade, separately. The trees, within each the pairwise genetic distances, did not support Hu's classification. Authors suggested that A. lancea Subsp. luotianensis should be included in A. lancea rather than be treated as a separate subspecies. A. carlinoides was placed in the basal position of Atractylodes, which had a distant relationship with the others of the genus. The results lead us to suggest that A. chinensis var. liaotungensis be put into A. coreana, A. chinensis as a subspecies of A. lancea.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...
