Men·del's law AHD[mĕnʹdlz] D.J.[ˈmendlz]K.K.[ˈmɛndļz]n.（名词）  Mendel's lawMendel's First Law: When a plant with two dominant (DD) alleles is crossed with a plant having two recessive (rr) alleles (top row), the first generation of plants (middle row) will all have one dominant and one recessive (Dr) allele. In the second generation (bottom row), on average one of four plants will have two recessive alleles. - One of two principles of heredity first formulated by Gregor Mendel, founded on his experiments with pea plants and stating that the members of a pair of homologous chromosomes segregate during meiosis and are distributed to different gametes. Also called law of segregation 孟德尔法则：格雷戈·孟德尔所创的之两个遗传定律之一，是在他用豌豆做实验的基础上创立的。他认为一对异体同形的染色体的各部分在减数分裂期间会相互分离，然后被分配到不同的配子体中 也作 law of segregation
- The second of these two principles, stating that each member of a pair of homologous chromosomes segregates during meiosis independently of the members of other pairs, so that alleles carried on different chromosomes are distributed randomly to the gametes. Also called law of independent assortment 孟德尔法则：这两条定律之第二条，认为每对染色体的各部分在减数分裂时都独立于其他染色体对的各部分而分离，以致于载有不同染色体的等位基因被随便地分配到配子体中 也作 law of independent assortment
