Clustering of upregulated or downregulated genes in type I, type II (or in both) arrested spermatocytes. K-means cluster analysis of DEGs between fertile (f), type I and type II spermatocytes reveals genes that are aberrantly expressed in type I arrested spermatocytes (clusters 1, 2), type II arrested spermatocytes (clusters 3, 4, 5) and in both type I and II arrested spermatocytes (clusters 6, 7, 8). Blue line represents the mean expression profile of genes in a cluster; profiles of individual genes are depicted by gray lines.
