a. T2T-Y has 44 TSPY protein-coding genes organized in a single continuous array and a single TSPY2 copy, compared to GRCh38-Y which has a gap in the TSPY array. T2T-Y shows a more regularized array and recovers additional TSPY pseudogenes not present in GRCh38-Y. b. Copy number differences of the TSPY protein-coding copies found in the SGDP. c, Repeat composition of the RBMY gene family. d. Repeat composition of the DAZ gene family, with one extra copy annotated on Chr3 that is missing L1PA2. While TSPY and RBMY genes are found within repeat composites forming arrays, DAZ-associated composites are embedded within the introns of the gene.
