Half-chromatid mutation as a possible cause of mosaic males and females in Hymenoptera and rare fertile male tortoiseshell cats.

Abstract excerpt

Half-chromatid mutations occur when a single base change in a gamete is transmitted to the zygote, which, after DNA replication and cleavage, will result in a mosaic individual.
