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，可以是纯显性（DD），也可以是杂显性（Dd），这两种情况会呈现出深色外观。

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

携带莱顿因V纯突变人，当然面更高凝血和出血风险。

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

一个则是杂黄色，纯圆形。

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

假设是隐性纯，比如说有50%生存几率。

Classify the following as heterozygous or homozygous.

将以内容分类为杂或纯。

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 代表是杂个体数量，而 q 平方则告诉我们纯隐性个体频率。

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这些信息，即浅色表型实际上是隐性纯（dd）。

The next one would be homozygous recessive.

一个将是纯隐性。

P squared stands for the individuals that are homozygous dominant.

P平方代表是纯显性个体。

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

那么这将是纯显性，这将是杂，而这则是纯隐性。

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

因此，第一个是杂，接着第二个是纯显性。

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

因此， 第一个，大写R大写R， 表示是纯显性。

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

我们几乎消除了这里纯隐性基因。
