What is wild type?In a population there are the prevalent varieties or characteristics that are more abundant than others. Meaning, the traits typical of the population. These pre-dominant characteristics are the wild type. Sometimes variations may appear in the said population. Some individuals will have different characteristics. These individuals are the mutants, individuals with characteristics different from normal. Therefore, the wild type are the characteristics of the most number of individuals in a population. In short, the prevailing traits of a population. The traits present in almost all of the individuals in a population are the wild type.

Yes, because, nature has its own way of selection aimed at ensuring the survival of the fit and elimination of the unfit. The species and populations that have survived in their respective environments have wild type traits that are fit, meaning fit for survival in the environment they belong. A population will survive for a long time, only if its wild type is suitable for survival. Because generation after generation greater number of the individuals in this population will survive and carry on the reproduction process, passing on good genes. These populations survive because their wild type traits are good and fit. If the wild type of a population is inferior, the population will become unfit for survival. Few individuals will survive and those few who somehow manage to survive will pass on bad genes, hence, fewer and fewer individuals will survive generation after generation. The population will eventually become extinct.
