Analysis of Chromatin in Male and Female Mealy Bugs
THE chromosome system of the mealy bug, Planococcus citri (= Pseudococcus ), is unique for the study of differences between heterochromatin and euchromatin. In the male, the paternal chromosomes are heterochromatic; that is, they remain condensed throughout interphase. In the female, both maternal a...

| description | THE chromosome system of the mealy bug,
Planococcus citri
(=
Pseudococcus
), is unique for the study of differences between heterochromatin and euchromatin. In the male, the paternal chromosomes are heterochromatic; that is, they remain condensed throughout interphase. In the female, both maternal and paternal sets are euchromatic. The paternal set behaves like heterochromatic sex chromosomes of other organisms; it reproduces asynchronously from the maternal or euchromatic set and is genetically inert

. Marker genes in the mealy bug are expressed in the male only if received from the mother (personal communication from S. W. Brown). X-ray damage to the heterochromatic set is not expressed
2
and the heterochromatic set is not labelled with tritiated uridine
