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因的因频率。

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

有突变不会影响有机体，有它们会产生全新的因。

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

是他们可能有不同的因，这些因是相同因的替代品。

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，允许合成毒蕈碱的因已经完全丢失或静默。

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

这一特殊的遗传学过程称为“记”，记因的存在使得两个因中的一个表达而另一个不表达。

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

正常情况下，来自亲本两方的因都会表达，而记因仅表达一方亲本来源的同源因。

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因，有些人拥有两个长型因，剩下的则长型短型各一个。

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

就像人类一样，犬科动物从每个父母那里继承一个特定因的因。

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

长因的参与者也有冒险的倾向，并屈服于酗酒成瘾行为。

Those seeds then start to grow, adding new alleles to our population's gene pool.

然后这些种子开始生长，为其种族因库增加新的因。

A similar situation can happen with gene flow, when new alleles are introduced to a population through migration.

类似的情况也会发生在因流动中——新的因通过迁徙被引入到一个群体之中。

The 'CYP17' gene which controls the body's level of sex hormones has a changed allele that is expressed frequently in trans man.

控制人体性激素水平的“CYP17”因的因发生了改变，这种改变在变性人中频繁发生。

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

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

The next steps will include how to release red wolves in a way that takes advantage of the ghost alleles hiding in coyote populations.

塞缪尔斯：接下来的步骤将包括如何利用隐藏在土狼种群中的幽灵因的方式释放红狼。

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，并导致新的因组合，这可能是有益的。

But if one or more of them occurs, evolution is possible, and those allele frequencies can start to change like symbols on a slot machine.

如果其中一个或多个发生了，进化就是可能发生的，这些因的频率就会像老虎机上的符号一样开始改变。

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因，那她的眼睛就是棕色的。如果你爸爸有两对蓝色眼睛的因，那他的眼睛就是蓝色的。

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.

这个家族中的许多物种直到现在都保留了合成毒蕈碱所需的因，家族中只有一小部分活的类属失去了这种特性。

Non-random mating won't change allele frequencies, but will change the combinations of alleles in a population, those pairings of two big C's, two little c's, or one big C and one little c.

非随机交配不会改变因的频率，会改变种群中因的组合，那些两个大 C，两个小 C，或者一个大 C 和一个小 C 的配对。

And one study found that 50% of people who possess the long allele variant of this gene had cheated on their partner, compared to only 22% of people who have the short allele.

一项研究发现，拥有该因的长因变体的人中有 50% 曾背叛过他们的伴侣，而拥有短因的人中只有 22% 的人出轨。
