Wild Type vs Mutant
野生型和突变类型是遗传学的术语,这些术语描述了根据遗传组成在生物体中表达的表型特征。当将这些术语一起考虑时,应在特定物种上给予注意力,因为只有在知道野生型之后,才能从人群中识别出突变类型。有足够的证据和例子可以理解这两个术语,并区分突变类型和野生型之间的差异。
Wild Type
Wild type is the phenotype expressed for a particular gene or set of genes in a species. In fact, the wild type is the most abundant phenotype among individuals of a particular species, which has been favoured by the natural selection. It has been formerly known as the expressed phenotype from the standard or the normal allele at a locus. However, the most prevalent phenotype has a tendency to vary according to the geographical or the environmental changes across the world. Therefore, the phenotype with the most occurrences has been defined as the wild type.
The golden yellowish fur with black colour stripes in Bengal Tiger, black spots on pale golden fur in leopards and jaguars are some classic examples for wild type phenotypes. The agouti coloured fur (brown and black bands on each hair shaft) is the wild type of many rodents and rabbits. It would be important to notice that the wild type could be different across one species as humans have different skin colours in Negroid, Mongoloid, and Caucasoid. The variation in the wild type based on the population could be mainly due to the geographical and other genetic causes. However, in a particular population, there could be only one wild type.
Mutant Type
Mutant type is a phenotype resulted off a mutation. In other words, any phenotype other than the wild type could be described as a mutant type. There could be one or many mutant type phenotypes in a population. White tiger has black stripes in white colour background of fur, and that is a mutant type. Additionally, there could be albino tigers with the entire fur being white coloured. Both these colourations are not common for Bengal tigers, which are mutant types. Panther or the melanistic form of big cats is also a mutant type.
Mutant types have a great importance when it comes to evolution as they become important to create a new species with different characters. It should be stated that individuals with genetic disorders are not mutant types. Mutant types do not have the most common occurrence in a population but very few. If the mutant type becomes dominant over other phenotypes, it will be the wild type afterwards. As an example, if there were more night time than daytime, then the panthers would become more prevalent than others through natural selection, since they can hunt unseen in the night. After that, the once mutant type panther becomes the wild type.
What is the difference between Wild Type and Mutant Type?
p•野生型是最常见的henotype in a population while mutant type could be the least common phenotype.
• There could be one or many mutant types in a population while there is only one wild type in a particular population.
• Wild type could be varied based on the genetic makeup and the geographical differences, whereas mutant type could be a variation only from the others.
•突变类型通过创建新物种有助于进化,而野生类型对进化没有很大的影响。
