Meiotic and sperm aneuploidy studies in three carriers of Robertsonian translocations and small supernumerary marker chromosomes

摘要

Objective: To study the meiotic behaviour of one carrier of a small supernumerary marker chromosome (sSMC): 47,XY,+mar; one carrier of a Robertsonian translocation (ROB): 45, XY, rob(13; 21) (q10;q10); and one carrier of both a sSMC and a ROB: 46, XY, rob(13; 21) (q11.1;q11.1), +mar.
