  • 2004
The study of mitotically unstable B-chromosomes (supernumeraries) of two grasshopper species confirmed a suggestion made earlier (Nur, 1963) that the instability should always be associated with aExpand

A "selfish" B chromosome that enhances its transmission by eliminating the paternal genome.
In the parasitic wasp, Nasonia vitripennis, males are haploid and usually develop from unfertilized eggs, whereas females are diploid and develop from fertilized eggs. Some individuals in thisExpand

An extrachromosomal factor causing loss of paternal chromosomes
Extrachromosomal inheritance is ubiquitous among plants and animals; however, most extrachromosomal factors are uniparentally inherited through females, but not through males1. Examples includeExpand

Selfish genetic elements.
Complex genetic systems appear to be inherently vulnerable to subversion by 'selfish' genetic elements, which gain a transmission advantage relative to the rest of the genome and are oftenExpand

  • 1 April 1990
In several families of scale insects (coccids), the sex of an embryo is determined by the number of genetically active genomes present (one = males, two = females). In mealybugs (Pseudococcidae),Expand

  • 30 November 1977
About 10-15% of the males and females of the grasshopper Melanoplus femur-rubrum collected near Rochester, New York, possessed a supernumerary B chromosome. The frequency of the B chromosome remainedExpand
