Answer :
All of the statements are true concerning mutations except A. Mutations must be present in parents and then passed to offspring, this is not always the case.
Answer: The correct answer is- A) Mutations must be present in parents and then passed to offspring.
Mutation can be described as the permanent change in the genetic material ( DNA) of an organism. It can be beneficial or harmful to the life form. Mutations can be heritable ( that is passed from one generation to the next) or non inheritable ( not passed from parents to offsprings).
A silent mutation ( change in the nucleotide sequence without any change in the amino acid sequence) that does not show any observable effects in the phenotype of the organism.
Thus, only option A) is not true about mutation.
