• Except for differences in primary structure, these molecules are similar in all species .
  这些分子中除了初级结构不同之外，在任何物种中别无二致。
• He first gives in detail all the many points of structure which vary in the several species .
  他首先就若干物种详细举出其在构造上的许多变异情况。
• They will not be haunted by the shadowy doubt whether this or that form be a true species .
  他们不会再被这个或那个类型是否是真实物种这个疑影所纠缠。
• Interspecific hybrids are obtained by fusing two different cell types from the one species .
  种内的杂种细胞是通过同一物种两种不同类型细胞融合而得的。
• Probably density-independent factors are more important at the edge of the range of a species .
  可能，在某物种的分布区的边缘，非密度制约因素最为重要。
• The basic set of chromosomes in a species is the haploid set, usually found in the gametes .
  一个物种染色体的基本数目是一个单倍体组，这通常见于配子中。
• Formations are often divided into subordinate community types characterized by their dominant species .
  群系可以按其优势物种的特征划分为一些次级的群落类型。
• The loss of one species' chromosomes from a hybrid in this way results in chromosomes segregation .
  杂种细胞以这种方式丢失一个物种染色体就导致染色体分离现象。
• Chromosome numbers which deviate from the normal number of chromosomes for a species are said to be heteroploid .
  偏离了一个物种的整个染色体数目的叫做导倍体。
