Question

All of the statements EXCEPT one are true about mutations. Which statement is false? A)Mutations must be present in parents and then passed to offspring. B)Mutations can be positive and produce organisms with improved traits. C)Mutations can be fatal to the organism that has a mutation, if the mutation is in a critical gene. Eliminate D)Mutations can be silent, and not affect the organism that has them, if the mutation is in a non-critical area.

Answer 1

Mutations must be present in parents and then passed to offspring. It IS possible for parents to pass on a mutation, if there is an error in meiosis or in the processes that create sperm or eggs. But mutations may arise directly in the offspring's DNA.

Answer 2

The statement that is FALSE is the A), that mutations must be present in parents and then passed to off srping. Mutations results from random errors in the replication of the DNA and some mutations can be inherited but others no. So mutations are not necessarily present in parents.
