A study of a small Y chromosome, found in a family line established in Canada since 1664, and traced back in France in some descendants of a sixteenth century ancestor related to the canadian one, has shown, by C-, G- and Q-banding techniques, that it was deleted of the q12 segment. This study suggests that the del(Y)(q12) results from the oldest known chromosome aberration.
对一条小Y染色体的研究发现，自1664年起在加拿大建立的一个家族谱系中存在该染色体，并且在一些与加拿大那个家族有亲缘关系的16世纪法国祖先的后代中也能追溯到。通过C带、G带和Q带技术研究表明，它缺失了q12区段。这项研究表明，Y染色体q12区段缺失是已知最古老的染色体畸变导致的。
