摘要: Sperm chromosome complements from two males, one heterozygous for the reciprocal translocation t(2;17)(q35;p13) (n = 18) and t(3;8) (p13;p21) 73), were analyzed. Only 2:2 segregations observed with t(2;17): alternate, 56%; adjacent-I, 33%; adjacent-II, 11%. Both 3:1 meiotic occurred in t(3;8): 34.2%; 43.8%; 20.5% 3:1, 1.4%. A significant excess of chromosomally normal versus balanced sperm was both heterozygotes. The frequencies other aberrations unrelated to translocations 16.7% t(2;17) 8.2% t(3;8). ratio X-bearing Y-bearing not different theoretically expected 1:1.
