Chromosomal localization of cotransformed transgenes in the hexaploid cultivated oat Avena sativa L. using fluorescence in situ hybridization.

abstract：:Red deer representing the four different European subspecies Cervus elaphus atlanticus, C. e. elaphus, C. e. germanicus, and C. e. scoticus were examined for allozyme variability at 35 enzyme loci. The proportion of polymorphic loci within populations (P) ranged from 0 to 13.8 per cent and the average heterozygosity (...
