Abstract
A cytogenetic study of the meiotic chromosomes of the budding yeast Saccharomyces cerevisiae was undertaken by high resolution epifluorescence microscopy. Condensation of chromatin into separate chromosomes takes place during prophase I. At metaphase I, there are 16 separate and distinct bivalents which are roughly classified into three groups by morphological differences and DNA content.
摘要
通过高分辨率落射荧光显微镜对出芽酵母酿酒酵母减数分裂染色体进行了细胞遗传学研究。在减数第一次分裂前期，染色质凝聚成单独的染色体。在减数第一次分裂中期，有16个单独且不同的二价体，根据形态差异和DNA含量大致分为三组。
