Ultrastructural analysis of chromatin in meiosis I + II of rye (Secale cereale L.).

abstract：:The catarrhine primates were the first group of species studied with comparative molecular cytogenetics. Many of the fundamental techniques and principles of analysis were initially applied to comparisons in these primates, including interspecific chromosome painting, reciprocal chromosome painting and the extensive u...
