Abstract:
The Y chromosomes of Drosophila are necessary for male fertility. They carry giant genes that have some unconventional properties besides controlling the motility of the spermatozoa. Classical genetic and molecular studies suggest that evolution has favoured the close association between these genes and repetitive DNA sequences with 'selfish' traits.
