A viable sex-linked homozygous translocation was isolated in Anopheles albimanus Wiedemann by using cytogenetic techniques and the X-linked marker, white eye. An examination of the meiotic chromosomes from ovaries established that the long arm of the X chromosome is involved in the translocation, and preparations of salivary gland chromosomes were used to confirm that the translocated arm of the meiotic X chromosome contains both euchromatin and heterochromatin. The translocated heterochromatin of the polytene X chromosome did not demonstrate an affinity for the chromocenter.
通过细胞遗传学技术和X连锁标记白眼,在白纹伊蚊中分离出一种可行的性连锁纯合易位。对卵巢减数分裂染色体的检查确定X染色体的长臂参与了易位,并且使用唾液腺染色体标本证实减数分裂X染色体的易位臂同时包含常染色质和异染色质。多线X染色体的易位异染色质对染色中心没有亲和力。
