7 results for “reciprocal translocation”
Data from: A reciprocal translocation radically reshapes sex-linked inheritance in the common frog
X and Y chromosomes can diverge when rearrangements block recombination between them. Here we present the first genomic view of a reciprocal translocation that causes two physically unconnected pairs of chromosomes to be coinherited as sex chromosomes. In a population of the common frog (Rana temporaria), both pairs of X and Y chromosomes show extensive sequence differentiation, but not degeneration of the Ys. A new method based on gene trees shows both chromosomes are sex-linked. Further, the gene trees from the two Y chromosomes have identical topologies, showing they have been coinherited since the reciprocal translocation occurred. Reciprocal translocations can thus reshape sex linkage on a much grander scale than do inversions, the type of rearrangement that is much better known in sex chromosome evolution, and they can greatly amplify the power of sexually antagonistic selection to drive genomic rearrangement. Two other populations show evidence of yet other rearrangements, suggesting that this species has unprecedented structural polymorphism in its sex chromosomes.
