因此产生不同的表现型态。

他们拥有相同隐性基因的几率很低。

PKU is an autosomal recessive genetic disorder that affects function of the phenylalanine hydroxylase enzyme.

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

第般类型的突变，隐性突变，其特该对中的两个基因都被破坏。

It could be the result of a recessive gene, a so-matic mutation, the influence of environment, or any combination of the three.

它可能是由个隐性基因表达、个体细胞基因突变、受环境影响或由以上三个因素任意结合而导致的结果。

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

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

这变异以常染色体隐性遗传方式遗传，只有同时遗传父母双方的突变基因才会患病。

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

得！快速回顾下：α地中海贫血是常染色体隐性遗传病，由16号染色体上的α珠蛋白基因缺陷引起。

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基因是隐性i的，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 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，许多特定的疾病或症状都是是隐性的，需要你同时从父母那里获得这些隐性基因。

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隐性等位基因才能表现出来的特。这情况下，你要有两个蓝色等位基因，才会有蓝色的眼睛。

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年才第次出现英国的本医学词典——虽然发明了“显性的”和“劣性的”这样的概念。

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是常染色体隐形遗传病，涉及CFTR基因；CFTR代表跨膜传导调节基因，它编码了CFTR蛋白。

A theory might invoke dominant and recessive genes to explain how brown-haired parents ended up with a red-headed child, or use gravity to shed light on the parabolic trajectory of a baseball.

个理论可能会引入显性和隐性基因来解释为什么棕色头发的父母 会生出红色头发的小孩，或者运用重力来阐释棒球的抛物线轨迹。

TSD is an autosomal recessive genetic condition, so males and females are affected equally, inheriting one mutated HEX-A gene from each asymptomatic or heterozygous parent in order to develop the homozygous condition.

Tay-Sachs病是常染色体隐性遗传病，因此男性和女性发病概率相等；患者分别从无症状的杂合子父母那里获得个突变的HEX-A基因，形成个纯合子。

专家们仍然不确定为什么会发生这情况，但他们认为四叶草可能是罕见的隐性基因或三叶草植物 DNA 基因突变的结果。

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.
