Distribution of ampliconic loci along the Y Chromosomes of five divergent felids. (A) FISH with probes designed for known ampliconic genes in metaphase preparations of several felid species. (B) Ideograms for each species with the predicted distribution of each ampliconic Y-linked gene indicated. Note the long arm of the Tigrina Y contains a substantial amount of sequence in which no known ampliconic genes were identified. (*) TSPY1 appears to be present along the long arm of the snow leopard Y, but it should be noted that the signal intensity of this probe was not as strong as other ampliconic genes expanded throughout this region.
