genotype和phenotype的区别基因型与表型的核心区别在于,前者是生物体遗传信息的内部基础,后者是遗传与环境共同作用下的外在表现。具体差异主要体现在定义、决定因素、可观察性及稳定性等方面。 一、定义与本质不同 基因型指生物体携带的特定基因组合,由DNA序列决定,代表遗传信息的潜在...
Genotype：指生物体的遗传组成，即其基因的具体等位基因组合。Phenotype：指生物体可观察到的特征或性状，这些特征由基因型与环境因素共同作用决定。等位基因对表现型的影响：显性等位基因：无论处于纯合子还是杂合子状态，都对表现型有明显影响。隐性等位基因：仅在纯合子状态下影响表现型。共显性等位基因...
1.phenotype侧重点：指后天形成的。2.genotype侧重点：指先天携带的。

4.3.1 Define genotype, phenotype, dominant allele, recessive allele, co-dominant alleles,, homozygous, heterozygous, carrier and test cross. Genotype: the alleles of an organism. Phenotype: the characteristics of an organism. Dominant allele: an allele that has the same effect on the phenotype wh...

The genotype of the individual determines the phenotype. However, it is not always possible to know the genotype by looking only at the phenotype. Using the purple-flowered pea plant example above, there is no way to know by looking at a single plant whether the genotype is made up of two...
Dissecting the relationship between genotype and phenotype is one of the central goals in developmental biology and medicine. 解剖基因型与表型之间的关系是在发育生物学和医学的主要目标之一。 www.syyxw.com 8. The M. tuberculosis strains studied showed no correlation between the virulence, viability, an...
Phenotype The outer appearance of an organism or the visible physical characteristics are known as phenotypes. When genes express themselves externally, that is the phenotype of that organism. It is like the “final product” that is shaped by our genes and the environment we live in. It includ...
