Since this is linked to the X chromosome, both Duchenne and Becker muscular dystrophy are called X-linked recessive.

由于发病与X染色体有关联，DMD和BMD被称为X连锁遗传。

具体来说， 肢端皮肤脱皮综合征是以常染色体式遗传。

The second general type of mutation, recessive mutation, is characterized by both genes in the pair being damaged.

第二种一般类型突变，即突变，其特征在于该对中两个基因都被破坏。

Sickle cell is an autosomal recessive disease, so a mutation in both copies of the beta-globin gene is needed to get the disease.

镰贫是一种常染色体遗传病，因此需要两个β-珠蛋白基因序列均突变才能获得该病。

The mutations are inherited in an autosomal recessive pattern, which means that you need mutated genes from both parents to get the disease.

这种变异以常染色体遗传式遗传，即只有同时遗传父母双突变基因才会患病。

All right, as a quick recap: alpha thalassemia is an autosomal recessive disorder caused by deletion of alpha globin genes on chromosome 16.

得！快速回顾一下：α地中海贫血是一种常染色体遗传病，由16号染色体上α珠蛋白基因缺陷引起。

It turns out that many specific diseases, or disorders, are recessive and require you to get the gene from both your mother and father.

事实证明，许多特定疾病或症状都是是，需要你同时从父母那里获得这些基因。

The O allele is recessive, so either of the others will override it when they're paired, resulting in either type A or type B.

O基因是i，所以当它和其他基因配对时都将被覆盖，成为A型血或B型血。

It takes having two recessive alleles to exhibit the other traits in this case if you got two blue alleles, you'd end up having blue eyes.

蓝色眼睛是需要有两个等位基因才能表现出来特征。在这种情况下，你要有两个蓝色等位基因，才会有蓝色眼睛。

He never used the word gene - it wasn't coined until 1913, in an English medical dictionary - though he did invent the terms dominant and recessive.

他从未用过“基因”这个词——这个词1913才第一次出现于英国一本医学词典——虽然发明了“显”和“劣”这样概念。

CF is an autosomal recessive disorder involving the CFTR gene, which stands for " cystic fibrosis transmembrane conductance regulator, " and this gene codes for the CFTR protein.

CF是一种常染色体形遗传病，涉及CFTR基因；CFTR代表跨膜传导调节基因，它编码了CFTR蛋白。

CF develops when there's a mutation in the CFTR gene, but because it's autosomal recessive, you need to inherit two mutated CFTR genes, one from mom and one from dad.

CFTR基因突变时会产生CF，但它是常染色体形遗传；患者体内两条CFTR突变基因，一条来自母亲，另一条来自父亲。

As a quick recap: sickle cell disease is an autosomal recessive genetic disease where the beta-globin subunit of hemoglobin is misshapen, which causes red blood cells to sickle when deoxygenated.

好！简要回顾一下：镰状细胞病，是常染色体遗传病，其中血红蛋白β-珠蛋白发生突变，脱氧情况下会导致红细胞镰变。

So, we know if you have offspring with someone genetically close to you like a sister or a cousin, it might mean that the child inherits two recessive genes.

所以， 我们知道， 如果您后代与遗传上与您亲近人（ 如姐妹或表亲）生育， 这可能意味着该孩子遗传了两个基因。

The brown color variant is the genetically dominant form of plumage in this species, but historically, the recessive pale gray variant triumphed because of its selective advantage in helping these predators blend in.

这种棕色变异是这种物种显状，但历史上，是浅灰色状占了上风因为这些有选择特殊优势，这些捕食者得以融入环境。
