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

但是他们可能有不同等位基因，这等位基因是相同基因替代品。

Notice the G allele may be the culprit here.

注意，G等位基因可能才是罪魁祸首。

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

所以，有拥有两个短型等位基因，有拥有两个长型等位基因，剩下则长型短型各一个。

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

我们每一种基因都有不同形式，称为等位基因。

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。

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

对于每个基因，类从每个亲本遗传一个等位基因，许多植物也是如此。

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

等位基因相互作用产生性状，或生物体可见特征。

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.

在这两个类属中，允许合成毒蕈碱等位基因已经完全丢失或静默。

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

类拥有别来自父亲与母亲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）。

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

正常情况下，来自亲本两方等位基因都会表达，而印记基因仅表达一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.

这一特殊遗传学过程称为“印记”，印记基因存在使得两个等位基因中一个表达而另一个不表达。

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等位基因变化！

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

就像类一样，犬科动物从每个父母那里继承一个特定基因等位基因。

But why are these called " ghost" alleles?

但为什么这被称为“幽灵”等位基因呢？

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等位基因。

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

这就是这个群体中番茄颜色基因等位基因频率。

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，称为等位基因，它们都起作用，但可能产生一不同效果。

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

长等位基因参与者也有冒险倾向，并屈服于酗酒等成瘾行为。

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等位基因，而来自你母亲染色体可能携带绿眼等位基因。
