Pan-European phylogeography of the aquatic snail Theodoxus fluviatilis (Gastropoda: Neritidae).
Investigating the geographical distribution of genetic lineages within species is critical to our understanding of how species evolve. As many species inhabit large and complex ranges, it is important that phylogeographical research take into account the entire range of widespread species to clarify how myriad extrinsic variables have affected their evolutionary history. Using phylogenetic, nes...
متن کاملThe Sex-Determining Mechanism of Drosophila Miranda.
SERIES of recent papers (DOBZHANSKY 1935; DOBZHANSKY and A TAN 1936; DOBZHANSKY 1937)) has described the unusual and interesting features which characterize the breeding behavior of Drosophila miranda and especially its method of sex determination. These papers have also reported the results of hybridization of miranda with the closely related and better known species, Drosophila pseudoobscura,...
متن کاملComparative In silico Study of Sex-Determining Region Y (SRY) Protein Sequences Involved in Sex-Determining
Background: The SRY gene (SRY) provides instructions for making a transcription factor called the sex-determining region Y protein. The sex-determining region Y protein causes a fetus to develop as a male. In this study, SRY of 15 spices included of human, chimpanzee, dog, pig, rat, cattle, buffalo, goat, sheep, horse, zebra, frog, urial, dolphin and killer whale were used for determine of bioi...
متن کاملA case of sex reversal syndrome with sex-determining region (XX male).
We examined a 32-year-old man with a 4-year history of infertility. The man's sex life, male hair pattern, and penis were normal, and he had no history of erection problems. Left and right testicular volumes were 2 ml and 3 ml, respectively. Semen analysis showed no sperm. The endocrine panel revealed increased serum luteinizing hormone and follicle-stimulating hormone levels, and a normal seru...
