n.杂合子(基因有两种不同形式的生物)

A person who is heterozygous for a particular gene has two different alleles of that gene.
对于某个特定基因而言，一个异质性的个体拥有该基因的两个不同等位基因。
Heterozygosity contributes to genetic diversity within a population.
异质性有助于群体内的遗传多样性。
The heterozygote advantage refers to the situation where an individual with two different versions of a gene is more fit than homozygotes.
异质性优势是指携带两种不同版本基因的个体相对于同型合子更具适应性的情况。
In sickle cell anaemia, individuals who are heterozygous for the mutation have some protection against malaria.
在镰状细胞贫血症中，对于突变基因呈杂合状态的个体对疟疾有一定的抵抗力。
When a plant is heterozygous for a recessive trait, it will not display that trait phenotypically.
当一株植物在隐性性状上为杂合时，它不会在外表上表现出这一性状。
Researchers studied the heterozygote frequency in the population for a specific genetic disorder.
研究人员研究了人群中某特定遗传病的杂合子频率。
Heterozygosity can lead to incomplete dominance or codominance in certain traits.
杂合性可能导致某些性状表现出不完全显性或共显性。
Inbreeding reduces the overall heterozygosity in a population, increasing the likelihood of expressing deleterious recessive traits.
近亲繁殖会降低群体的整体杂合性，增加表达有害隐性性状的可能性。
Through crossing-over during meiosis, a heterozygote may produce offspring with new combinations of alleles.
通过减数分裂过程中的交叉互换，杂合体可能产生带有新等位基因组合的后代。
Some plants exhibit heterosis, or hybrid vigor, when grown from seeds produced by a cross between two genetically diverse parents.
有些植物在双亲遗传差异较大的杂交种子发育成植株后会表现出杂种优势或杂种活力。
