Hinshelwood (1946), for example, has disregarded the selection of spontaneous mutants as an element of bacterial adaptations, apparently in order to bolster the applicability of his system of ...

Applied since the 1930s to accelerate the process of developing and selecting new valuable agronomic traits, mutation breeding uses a plant’s own genetic make-up, mimicking the natural process of ...

Still others proposed that spontaneous, random mutations, or changes, in organisms accounted for the variety of species. Natural selection was not needed in this explanation. It wasn't until the ...

A child who inherits the altered gene will also have the disorder. It’s important to determine whether the disorder is inherited or is the result of a spontaneous mutation, since an individual with an ...

Induced mutations occur at a much higher frequency than spontaneous mutations and therefore increase the chance of generating new desired traits in plants. The Section develops the capacities of ...

A purebred German Shepherd, she was the only puppy of the litter with white markings and neither parent had white markings, ...

The mutation in question—in which cytosine ... switched to thymine (T)—was thought to be primarily the result of a spontaneous chemical reaction with water. This reaction, deamination ...
