Paternal transmission of entire compounds of chromosome two in Drosophila melanogaster

Mol Gen Genet. 1982;187(1):126-31. doi: 10.1007/BF00384395.


In Drosophila melanogaster, entire compound second chromosomes (2R2L . 2L2R) consist of the entire amount of genetic material normally found on separate homologues, as well as significant amounts of heterochromatin derived from the Y chromosome, joined to a single centromere. Genetic analysis demonstrates that information carried upon the Y chromosome influences the rate of transmission of the compound in the male.
