In fact, if for some reason the number of chromosomes should vary from normal, vital functions are usually affected to the extent that the organism generally dies during embryonic development.

事实上，如果由于某种原因，染色体数目可能与正常不同，生命有机体通常受到影响，有机体一般在胚胎发育过程死亡掉。

The whole subject of gene segregation and recombination and their expression in the phenotype is sometimes referred to as Mendelian genetics.

有时把基因分离与基因重组及基因表达的所有问题都称为孟德尔遗传学。

This cross is special in that all possible kinds of genotypes that can exist in a system with only two alleles are present among the progeny.

这种杂交方式的特殊性在于，在后代中尽管只有两个等位基因，但所有可能的基因型都出现。If the two genes in any genotype are the same, as in AA and aa, their effects will be the same upon the phenotype. However, when the heterozygote is involved, we must consider the effects of both of these alleles.

如果两个等位基因相同，如AA,aa，它们对表现性的影响是同样的。但是，当涉及杂合子时，我们必须同时考虑两个等位基因间的作用。

Since the possibility exists that it could be heterozygous and still sire several rose-combed chicks before any single-combed ones appeared, five or ten or more progeny should be observed before deciding that the cock is homozygous.

由于杂合体公鸡在产生单冠之前，仍可能产生数只玫瑰冠鸡，因此，在判断该鸡是否是纯合体之前，应观察五只，十只或更多的F1代。

Food is material which, after ingestion by animals, is capable of being digested, absorbed and utilised. In a more general sense we use the term food to describe edible material.

饲料是被动物摄取之后能够被消化，吸收和利用的物质。一般来说，我们用饲料这一术语来描述可食用的物质。

Animals depend upon plants for their existence and consequently a study of animal nutrition must necessarily begin with the plant itself.

动物依赖植物而生存，对于动物营养物质的研究，首先必须从植物本省开始。

The greater part of the energy, however, is stored as chemical energy within the plant itself and it is this energy which is used by the animal for the maintenance of life and synthesis of its own body tissues.

植物可以通过光合作用，利用太阳能，但大部分能量以化学能的形式储存于植物体内，动物利用这种能量来维持生命和自身身体组织。

An important difference between plants and animals is that, whereas the former can synthesise all the vitamins they require for metabolism, animals cannot, or have very limited powers of synthesis, and are dependent upon an external supply.

动植物之间一个重要的区别是植物能够合成自身代谢所需要的全部维生素，而动物则不能或者说合成能力非常有限，主要依靠外源供给。

A system for approximating the value of a feed or material for feeding purposes, without actually using the feed in a feeding trial, was developed at the Weende Experiment Station in Germany over 100 years ago.

早在100年前，德国的Weende实验站发明了可不经过实际饲养实验，便可对饲料和原料成分进行近似评估的一套方案。
