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

但是他们可能有不同位基因，这些位基因是相同基因替代品。

Notice the G allele may be the culprit here.

注意，G位基因可能才是罪魁祸。

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

所以，有些人拥有两短型位基因，有些人拥有两长型位基因，剩下则长型短型各。

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

我们每种基因都有不同形式，称为位基因。

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

位基因是染色体上编码特定遗传特征部分。

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

对于每基因，人类从每亲本遗传位基因，许多植物也是如此。

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

位基因相互作用产生性状，或生物体可见特征。

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

拥有G位基因意味着你大脑中血清素含量较低。

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

在这两类属中，允许合成毒蕈碱位基因已完全丢失或静默。

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两血清素转运体基因，每基因有两种版本（被称为位基因）。

This differs from most genes in the genome, where both the maternal and paternal copies are expressed.

正常情况下，来自亲本两方位基因都会表达，而印记基因仅表达方亲本来源同源基因。

This special genetic process is called imprinting, where only one copy of the gene gets expressed, not both.

这特殊遗传学过程称为“印记”，印记基因存在使得两位基因中表达而另不表达。

The tornado was totally random, but resulted in major allele changes to the population!

这场龙卷风是完全随机，但导致了番茄种群主要位基因变化！

Just like humans, canines inherit one allele from each parent for a certain gene.

就像人类样，犬科动物从每父母那里继承特定基因位基因。

But why are these called " ghost" alleles?

但为什么这些被称为“幽灵”位基因呢？

Sometimes mutations don't affect an organism, but sometimes they can result in brand-new alleles.

有时突变不会影响有机体，但有时它们会产生全新位基因。

That's the allele frequency of the tomato color gene in that population.

这就是这群体中番茄颜色基因位基因频率。

Most genes have variants, known as alleles, which all work, but may have somewhat different effects.

大多数基因都有变体，称为位基因，它们都起作用，但可能产生些不同效果。

The long allele participants also had a tendency to be risk-takers and succumb to addictive behaviors such as alcoholism.

长位基因参与者也有冒险倾向，并屈服于酗酒成瘾行为。

So the chromosome from your dad may carry the blue eye allele, and the one from your mum may carry the green eye allele.

所以来自你父亲染色体可能携带蓝眼位基因，而来自你母亲染色体可能携带绿眼位基因。
