And so this first one, big R big R would be homozygous dominant.

因此， 第一个，大写R大写R， 表示的是纯。

P squared stands for the individuals that are homozygous dominant.

P平方代表的是纯个体。

People are homozygous mutants for factor V Leiden, of course, at much greater risk for clotting and bleeding.

携带莱顿因子V纯突变的人，当然面临更的凝血和出血风险。

Now we know this about moths, that the light phenotype is actually homozygous recessive (dd).

现在我们关于蛾子的这些信息，即浅色表型实际上是隐纯的（dd）。

Classify the following as heterozygous or homozygous.

将以下内容分类为杂子或纯子。

Then this would be homozygous dominant, this would be heterozygous and this is homozygous recessive.

那么这将是纯，这将是杂，而这则是纯隐。

And we have almost the elimination of that homozygous recessive down here.

我们几乎消除这里的纯隐基因。

So let's say if you're homozygous recessive, let's say you have a 50% chance of survival.

假设你是隐纯子，比如说你有50%的生存几率。

The next one would be homozygous recessive.

下一个将是纯隐。

And the next one would be homo, excuse me, heterozygous yellow, homozygous for the round.

下一个则是杂子的黄色，纯子的圆形。

So it's going to be heterozygous and then homozygous dominant on the next one.

因此，第一个是杂子，接着第二个是纯。

2pq stands for the individuals that are heterozygous and q squared tells us what individuals are, the frequency of the individuals that are homozygous recessive.

2pq 代表的是杂个体的数量，而 q 平方则告诉我们纯隐个体的频率。

And the dark appearance you can be either homozygous dominant (DD) or you can be heterozygous dominant (Dd) for that and you're going to have the dark appearance.

至于深色外观，你可以是纯（DD），也可以是杂（Dd），这两种情况下你都会呈现出深色外观。
