Somatic and egg squashes of Ctenocephalides orientis exhibited a chromosome complement of 2n = 14,XY/XX, whereas the spermatocytes showed 2n = 15,XY1 Y2. The sex trivalent was restricted to spermatogenesis; in oogenesis only one sex bivalent was formed. Elimination of one of the Y chromosomes from the somatic cells was evident.
东方栉头蚤的体细胞和卵压片显示其染色体组成为2n = 14，XY/XX，而精母细胞显示为2n = 15，XY1Y2。性三价体仅限于精子发生过程；在卵子发生过程中仅形成一个性二价体。体细胞中一条Y染色体的消除是明显的。
