DNA fails to copy accurately and external influences can create mutation
PKU (phenylketonuria) is a point mutation, specifically an autosomal recessive genetic disorder caused by a mutation in the PAH gene. This mutation leads to impaired metabolism of the amino acid phenylalanine. It is not a frameshift mutation, which would involve an insertion or deletion of nucleotides, shifting the reading frame of the gene.
The answer is a mutation. Its a mutation because a mutation can cause an organism to be deformed an in some cases due to the deformation it will not be able to feed or defend for it self. For example, if a Giraffe were to be born with a short neck it would not be able to feed because trees are tall
well.. his early influences we're you :D
Stress resulting from some outside pressure od just simple boredom.
external influences on phenotype
DNA fails to copy accurately and external influences can create mutation
If you ask wondering about Internal and External influences of a business there are many. Internal means things that the business can control, some of these include management, product, location, resources (meaning who they are buying the materials from, captial ect), and the business culture (how the business operates e.g. Green, Australian Made, ect). External influences also vary and could be economy, government, multicultralism, product diversity, competitors, market conditions, geographic and social. Though these are only a few, many other Internal and External Influences exist. Hope this helped :)
No. There are some psychedelic drugs that can mimic schizophrenia, but there is no known external cause.
it depends on what mutation you speak of. some are and some are not.

can some one write the reason for why external or internal?
i] spontaneous mutation ii] induced mutation iii] germinal mutation iv] somatic mutation v] chromosomal mutation vi] gene mutation are the some of the major types of mutation......
It depends on the mutation. Some mutations have no effect on survival, some mutations are lethal, and some mutations make an individual better adapted to its environment, so it will be more fit than those without the mutation, and therefore produce more offspring with the same mutation, which could change the allele frequency of a population.
Things that cause changes in supply are also called influences of supply. Some of these influences on supply are: cost of inputs, productivity, technology, taxes, subsidises, government regulation, numbers of sellers, war, and other political conflict.
Some mutations produce new traits that can help an organism survive.
