摘要: 本试验分析了四川麻鸭(Anas platyrbynchos domestica)的染色组型。染色体数目2n=80(♂、♀)。染色体基本臂数为86(♂)或85(♀)。性染色体为ZZ(♂)/ZW(♀)型。1号和2号染色体分别属亚中部(sm)和中部(m)着丝粒染色体。Z染色体(4号)属亚端部(st)着丝粒染色体。W染色体(大小相当于8号)和其余常染色体均属端着丝粒(T)染色体。

Abstract: The karyotype of partrige Sichuan Ducks was analysed. The diploid chromosome numbers are 80 (♂, ♀). The fundamental numbers are 86 (♂) or 85 (♀). The sex chromosome pattern is ZZ (♂)/ZW (♀). Chromosomes 1 and 2 are submetacentric and metacentric, respectively. Z chromosome (4 th) is subtelocentric. W chromosome (ranking 8th) and the other autosomes are telocentric.
