(18) A phylogenetic tree based on allelic variation detected electrophoretically at 20 enzyme-encoding loci revealed two major clusters and several deep branches composed of strains that synthesize msDNA.
(19) Sequence divergence in the 16S rRNA obtained from alignment with published insect sequences is consistent with phylogenetic hypotheses, in that Diptera and Lepidoptera are more closely related to each other (24% sequence divergence) than either is to Hymenoptera (31%).
(20) A differential, temporal and spatial expression of this epitope in metamorphosing nervous tissue was outlined, that apparently characterises homologous neuronal populations in two phylogenetically distinct holometabolous insects, i.e.
Phylogeny
Definition:
(n.) The history of genealogical development; the race history of an animal or vegetable type; the historic exolution of the phylon or tribe, in distinction from ontogeny, or the development of the individual organism, and from biogenesis, or life development generally.
Example Sentences:
(1) The sequence data were used to infer phylogeny by using a maximum-parsimony method, an evolutionary-distance method, and the evolutionary-parsimony method.
(2) The only inconsistency in the mariner gene phylogeny is in the placement of the Zaprionus mariner sequence, which clusters with mariner from Drosophila teissieri and Drosophila yakuba in the melanogaster species subgroup.
(3) The unique structure of these cilia has systematic and phylogenetic significance for the Acoela, and it is argued that ultrastructural characters in general, including characters of organelles, can be validly applied to the phylogeny and systematics of the Metazoa.
(4) In general, more than five loci are needed to resolve the species phylogeny.
(5) Genetic control of hormone receptors is analyzed by studying changes in their characteristics during the ontogeny, phylogeny, and malignant transformation of cells.
(6) Ecological changes on the main stem of the phylogeny are abrupt and associated character states consequently well differentiated.
(7) The data about genomic and protein sequences could provide bases to complement or expand the rRNA-based phylogeny.
(8) Therefore a primitive symmetrodont molar pattern was probably present in the phylogeny of pantotherian and tribosphenic molars.
(9) Recently published amino acid sequences are compared to those of other cytochromes c. Molecular phylogenies constructed by using an ancestral sequence method are compared to the classical biological view of invertebrate evolution.
