B chromosomes are often considered genomic parasites. Paternal sex ratio (PSR) is an extreme example of a parasitic B chromosome in the parasitoid waspNasonia vitripennis. PSR is transmitted through the sperm of carrier males and destroys the other paternal chromosomes in early fertilized eggs. PSR disrupts the normal haplodiploid sex determination in this wasp by converting diploid (female) eggs into haploid (male) eggs that bear PSR. In this study I compare a number of phenotypic fitness… CONTINUE READING
