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

因此， 第一个，大写R大写R， 表示合显。

P squared stands for the individuals that are homozygous dominant.

P平方代表合显个体。

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合突变人，当然面临更凝血和出血风险。

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

现在我们了解到关于蛾子这些信息，即浅色表型实际上合（dd）。

Classify the following as heterozygous or homozygous.

将以下内容分类为杂合子或合子。

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

那么这将合显，这将杂合，而这则合。

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

我们几乎消除了这里合基因。

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

假设你合子，比如说你有50%生存几率。

The next one would be homozygous recessive.

下一个将合。

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

下一个则杂合子黄色，合子圆形。

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

因此，第一个杂合子，接着第二个合显。

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 代表杂合个体数量，而 q 平方则告诉我们合个体频率。

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，你可以合显（DD），也可以杂合显（Dd），这两种情况下你都会呈现出深色外观。
