K-mer estimates from 1,597 males show human Yq12 heterochromatin spans ~1–52 Mb (mean 26.5 Mb) with strong within- and between-haplogroup variation.
- Why it matters: Population-scale analysis of megabase satellite arrays is difficult because complete, sample-specific assemblies are hard to obtain, limiting study of Yq12 evolution and function.
- What they did: The study built k-mer-based tools to infer Yq12 size from short- and long-read data using complete Y-chromosome assemblies, then analyzed 1,597 males from the 1000 Genomes Project and 303 father-son pairs.
- The result: In father-son pairs, fathers had longer estimated Yq12 in 70.6% of cases, and testis Iso-Seq plus single-cell RNA-seq detected DYZ1/2 transcripts in haploid spermatids.
