Isolation of a sex-linked homozygous translocation in Anopheles albimanus.
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.
