At anaphase the dicentric chromatid will form a bridge and the acentric a fragment, both of which can be scored . 在后期双着绿点染色体将形成一个桥,无着绿点染色体单体形成一断片,此两者均可记录下来。
There are 4 pairs central - region - kinomere chromosomes and 4 pairs subcentral - region - kinomere chromosomes and only one pair telochromosomes in one cell 4对为中部着丝点染色体, 4对为近中部着丝点染色体,只有1对近端部着丝点染色体。
