高中《生物》教材介绍孟德尔两对相对性状的遗传实验是选用了豌豆种子的颜色（黄色和绿色）和豌豆种子的形状（圆粒和皱粒）两对相对性状。其中，豌豆种子的颜色是指从种皮透出的子叶的颜色，它属种子胚的性状，种子的形状则属种皮的性状，在讨论它们的遗传问题时应该从它们的 High school “Biology” textbook introduces Mendel’s two pairs of relative traits genetic experiments using the color of pea seeds (yellow and green) and the shape of pea seeds (round and wrinkled grains) two pairs of relative traits. Among them, the color of the pea seed refers to the color of the cotyledon penetrating from the seed coat, it is the trait of the seed embryo, the shape of the seed is the trait of the seed coat, and their genetic issues should be discussed from their
