In truly doubtful cases, only test crosses will reveal the actual genotype . 在确实可疑的情况下,只有通过杂交试验才能揭示出真正的基因型。
Many trees can be propagated from vegetative shoots, thus reproducing their genotypes exactly . 许多树木能够利用营养枝繁殖,这样,它们的基因型可以精确地传衍。
In these cases, the parental cells differ at least with respect to genotype if not phenotype as well . 在这些情况下,亲本细胞即使不在表现型上至少也在基因型上有区别。
Differential temperature effects also were observed after measurement of tillering in infested and non-infested genotypes . 通过调查被害和未被害基因型的分蘖情况,也可以看到不同的温度效应。
