Using the coudé spectrograph of the NAO 2m telescope at the RhodopeMountains, Bulgaria, 9 spectra in the blue and 8 spectra in the red photographic region of P Cygni were obtained during 1990. By averaging the spectra in each set a S/N-ratio of about 45was achieved. Comparing the lists of identifications published by Beals (1950), de Groot (1969), Ozemre (1978), Stahl et al. (1993), Markova (19...

The current study was conducted to identify the quantitative trait locus (QTL) for the body weight at age 1, 7, 14, 21 and 28 days and daily gain at age 0-1, 1-2, 2-3 and 3-4 weeks, slighter carcass weight and tonic immobility in Japanese quail. Two divergently lines of wild and white Japanese quail which maintained in the Animal Science Research Center of the Shahid Bahonar University of Kerma...

The relation of recent work in genetics to the Darwinian theory is still in dispute. The value of the natural selection hypothesis can only be determined by appropriate experimental tests. At present there appears to be no inherent incompatibility between DARWIN’S fundamental principles and the newer concepts of pure lines, mutations, and unit characters. To some the action of natural selection...

Human psychophysical observations, computational models, and the selectivity of neurons in primary visual cortex all suggest that an early step in visual processing is the detection of features such as lines and edges. However, previous fMRI experiments investigating the responses of early visual areas to phase coherence have led to apparently discordant results. We studied the human brain BOLD...

An experimental line (F) of turkeys was reciprocally crossed with sire lines (designated A and B) from each of two commercial breeders in order to study the inheritance of carcass traits and body shape. The birds were weighed and killed at 17 wk of age, and various measurements of muscling, leg bones, and body shape were made. Additive genetic variation, as indicated by line differences, was an...
