Granulosus is further; 2. In differentiation of closely relatedspecies, the changes in heterochromatin and pericentric inversions are key factors, this is wellnoted in the small chromosomes; 3. A. mantzorum has well-differentiated XY type sex chromo-`.omes, the Y chromosome is mainly composed of euchromatin, but has strong C-band in themiddle of the long arm. It is suggested that the Y chromosome of A. mantzorum is in the-initial stage of sex chromosome differentiation.
结果表明：(1)四川湍蛙、理县湍蛙和棕点湍蛙之间的亲缘关系较近，而它们与棘皮湍蛙的亲缘关系较远；2）在近缘种的分化中，染色体结构异染色质的变化和臂间倒位是重要的因素之一，这在小型染色体上表现得尤为突出；四川湍蛙具有在形态上分化很明显的性染色体。C带分析表明，此性染色体主要由常染色质构成，但在其Y染色体的长臂上存在明显的中间C带，推测尚处于性染色体分化的初期阶段。
