Notice the G allele may be the culprit here.

注意，G等位基因可能才是罪魁祸首。

While the A and B alleles code for A and B antigens, the O allele codes for neither, and because we inherit one copy of each gene from each parent, every individual has two alleles determining blood type.

A和B基因进行编码成为A和B抗原，O基因则一个都不是。因为我们从每一个父母那继承了每个基因的复制品，每个人拥有两个决定血的等位基因。

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的等位基因。

The results of the study showed statistically significant differences in persistence scores, showing that subjects with the blood type A allele were more persistent.

究的结果显示，在持久性得分上有统计学上的显著差异，表明具有A等位基因的受试者更持久。

Many species within this family have conserved the alleles required to synthesizing muscarine until the present day, with a smaller subset of living genera within this family to lose this trait.

个家族中的许多物种在都保留了合成毒蕈碱所需的等位基因，家族中只有一小部分活的类属失去了种特性。

The new combinations of DNA created during crossover are a significant source of genetic variation, and result in new combinations of alleles, which may be beneficial.

在交换过程中产生的新的 DNA 组合是遗传变异的一个重要来源，并导致新的等位基因组合，可能是有益的。

Now, the fact that both Duchenne and Becker muscular dystrophy result from mutations in the same dystrophin gene means that they are " allelic disorders, "

DMD和BMD都是由于同一抗肌萎缩蛋白基因突变引起的，意味着二者是“等位基因疾病”。

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

所以来自你父亲的染色体可能携带蓝眼等位基因，而来自你母亲的染色体可能携带绿眼等位基因。

But the business of passing on alleles and saving humanity really begins in the basic reproductive units in the cortex — the ovarian follicles.

但是传递等位基因和拯救人类的事业真正开始于皮层的基本生殖单位——卵巢卵泡。

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

所以，有些人拥有两个短等位基因，有些人拥有两个长等位基因，剩下的则长短各一个。

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

一特殊的遗传学过程称为“印记”，印记基因的存在使得两个等位基因中的一个表达而另一个不表达。

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）。

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，些等位基因是相同基因的替代品。

It also includes the glands, ducts, external genitalia, and particular brain parts that help the gonads and gametes do what they need to do, which basically is mate, combine alleles, and make babies.

它还包括腺体、导管、外生殖器，以及帮助性腺和配子做它们需要做的事情的特定大脑部分，基本上是交配、结合等位基因和生育。

If your mom has two pairs of the brown eye allele, her eyes will be brown, and if your dad has two pairs for the blue eyes, his will be blue.

如果你妈妈有两对棕色眼睛的等位基因，那她的眼睛就是棕色的。如果你爸爸有两对蓝色眼睛的等位基因，那他的眼睛就是蓝色的。

Say there's a gene that tells a tomato what color to be, and it comes in two alleles, big C and little c.

假设有一个基因决定番茄的颜色，它有两个等位基因，大 C 和小 C。

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

在两个类属中，允许合成毒蕈碱的等位基因已经完全丢失或静默。

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

正常情况下，来自亲本两方的等位基因都会表达，而印记基因仅表达一方亲本来源的同源基因。

This process of adding more repeats is called repeat expansion and it happens way more in the production of sperm than of eggs, so both anticipation and new disease alleles generally happens when the father is the affected parent.

种序列重复增加称为重复序列扩增，精子产生时发生异常的几率比卵子高，因此当父亲为受累个体时，会发生早象和新的疾病等位基因。

When it comes to your reproductive system, it's not concerned about you, so much as it is about your alleles, your genetic code, and the future of the human species.

当涉及你的生殖系统时，它不关心你，而是关心你的等位基因，你的遗传密码，以及人类物种的未来。
