But they may have different alleles, which are alternatives of the same genes.

但是他们可能有不同的等位基因，这些等位基因是相同基因的替代品。

So some have two short alleles, some have two long ones, and the rest have one of each.

所以，有些人拥有两个短型等位基因，有些人拥有两个长型等位基因，剩下的则长型短型各一个。

Each of our genes can come in different flavors, called alleles.

我们的每一种基因都有不同的形式，称为等位基因。

People have two versions (known as alleles) of each gene, one from each parent.

人类拥有分别来自父亲与母亲的两个血清素转运体基因，每个基因有两种版本（被称为等位基因）。

For each gene, humans inherit one allele from each parent, and many plants do, too.

对于每个基因，人类从每个亲本遗传一个等位基因，许多植物也是如此。

Notice the G allele may be the culprit here.

注意，G等位基因可能才是罪魁祸首。

In these two genera, the alleles that allow the synthesis of muscarine, have been completely lost, or silenced.

在这两个类属中，允许合成毒蕈碱的等位基因已经完全丢失或静默。

Alleles interact to produce traits, or the visible characteristics of an organism.

等位基因相互作用产生性状，或生物体的可见特征。

Alleles are the parts of a chromosome that encode specific genetic traits.

等位基因是染色体上编码特定遗传特征的部分。

Having the G allele means you'll have a lower level of serotonin in your brain.

拥有G等位基因意味着你大脑中的血清素含量较低。
