Autosomal mutations affecting Y chromosome loops in Drosophila melanogaster
Abstract Background The Y Wooden Bar chromosome of Drosophila melanogaster harbors several genes required for male fertility.The genes for these fertility factors are very large in size and contain conspicuous amounts of repetitive DNA and transposons.Three of these loci (ks-1, kl-3 and kl-5) have the ability to develop giant lampbrush-like loops i
