Comparative molecular phylogeny and evolution of sex chromosome DNA sequences in the family Canidae (Mammalia: Carnivora).
To investigate the molecular phylogeny and evolution of the family Canidae, nucleotide sequences of the zinc-finger-protein gene on the Y chromosome (ZFY, 924-1146 bp) and its homologous gene on the X chromosome (ZFX, 834-839 bp) for twelve canid species were determined. The phylogenetic relationships among species reconstructed by the paternal ZFY sequences closely agreed with those by mtDNA a...
متن کاملCHROMOSOME STUDIES OF IRANIAN MEMBERS OF TRIBE SOPHOREAE (FAMILY LEGUMINOSAE
The tribe Sophoreae sensu Polhill [9,10] is a large and diverse assemblage comprising the ancient and primitive ancestral stocks of Papilionoideae. The most frequent chromosome basic numbers in this tribe are x = 11 and x = 9 but chromosome numbers range from x = 8-14 are also known. In this study chromosome numbers and karyotype variation of Iranian members of tribe Sophoreae are reported. Ira...
متن کاملMolecular systematics of the Canidae.
Despite numerous systematic studies, the relationships among many species within the dog family, Canidae, remain unresolved. Two problems of broad evolutionary significance are the origins of the taxonomically rich canidae fauna of South America and the development in three species of the trenchant heel, a unique meat-cutting blade on the lower first molar. The first problem is of interest beca...
متن کاملUse of RAPD technique in evolution studies of four species in the family Canidae.
The RAPD-PCR technique was applied to identify genetic markers able to distinguish between four canid species: the arctic fox (Alopex lagopus), red fox (Vulpes vulpes), Chinese raccoon dog (Nyctereutes procyonoides procyonoides) and six breeds of the domestic dog (Canis familiaris). A total of 29 ten-nucleotide arbitrary primers were screened for their potential use in the differentiation of th...
متن کاملThe Chromosome Complex
MISS STEVENS, in a paper entitled " The Chromosomes in the Germ-Cells of Culex," gave as one of her conclusions the following : "Parasynapsis (parasyndesis) occurs in each cell generation of the germ-cells, the homologous maternal and paternal chromosomes being paired in telophase and remaining so until the metaphase of the next mitosis." Because of the importance of this discovery, especially ...
