下列动物行为中．属于后天性行为的是
A．鸟类孵卵
B．鱼类洄游
C．狗做“算术”
D．蜜蜂采蜜
答案：C
题目分析：先天性行为是指动物生来就有的，由动物体内的遗传物质所决定的行为，称为先天性行为，例如：蜜蜂采蜜，蚂蚁建巢，蜘蛛织网，鸟类迁徙等， 先天性行为是动物的一种本能行为，不会丧失；后天性行为是动物出生后通过学习得来的行为，动物建立后天行为的主要方式是条件反射，参与神经中枢是大脑皮层，不是与生俱来的而是动物在成长过程中，通过生活经验和“学习”逐渐建立起来的新的行为。狗做“算术”是通过学习训练得来的行为，属于后天性行为，鸟类孵卵、鱼类洄游、蜜蜂采蜜，是生来就有的，不学就会的，由体内的遗传物质所决定的先天性行为。
点评：此题为基础题，解答此类题目的关键是理解动物行为获得途径和特点。
