But a hybrid partakes of only half of the nature and constitution of its mother; it may therefore, before birth, as long as it is nourished within its mother's womb, or within the egg or seed produced by the mother, be exposed to conditions in some degree unsuitable, and consequently be liable to perish at an early period; more especially as all very young beings are eminently sensitive to injurious or unnatural conditions of life.
Baina hibridoak amaren izaera eta osaeratik erdia besterik ez du, eta horregatik, jaio aurretik, amaren umetokian, edo amak sorturiko hazian edo arrautzan elikatzen ari den denbora guztian, bizi-baldintza neurriren batean desegokietan izan daiteke, eta, beraz, aldi goiztiarrean hiltzeko arriskuan, batez ere izaki gazte-gazte guztiak bizi-baldintza kaltegarri eta antinaturalekiko oso sentiberak direlako.
