Abstract

The formation of constitutive heterochromatin was studied during the embryonic development of Drosophila melanogaster, using the C-banding technique. During embryonic cleavage, C-banded material is not seen in mitotic chromosomes; the differentiation between euchromatin and heterochromatin only occurs at blastoderm. This event correlates with the establishment of position-effect variegation.

摘要

利用C带技术，研究了黑腹果蝇胚胎发育过程中组成型异染色质的形成。在胚胎卵裂期间，有丝分裂染色体中未见C带物质；常染色质和异染色质之间的分化仅发生在胚盘形成期。这一事件与位置效应斑驳的建立相关。
