.... indutus ), only terminal telomeres were observed, whereas in species experiencing intense chromosomal evolution (e.g., M. minutoides , M. musculoides ), a large amplification of telomeric repeats was also identified in the pericentromeric region of acrocentrics and most metacentrics. We concluded that (i...
