性染色体在家鼩（Suncus murinus）减数分裂过程中的行为表现出一些有趣的特征。X染色体和Y染色体都很大，有两条臂，在非着丝粒区域有巨大的C带片段。在X染色体和Y染色体的短臂之间形成明显的交叉，二价体中的异染色质区域以凸起的形式显示出联会消失。
The behavior of the sex chromosomes during meiosis in the house shrew, Suncus murinus, shows some interesting features. Both X- and Y-chromosomes are large and biarmed and have huge segments of C-band material in noncentromeric areas. A distinct chiasma is formed between the short arms of the X and Y chromosomes and the heterochromatic regions in the bivalents show desynapsis in the form of a bulge.
