Are genetic mutations always harmful to the individual?
Genetic mutations are not always harmful to the individual. A few may be beneficial.
Are all mutation harmful?
Mutations that succeed [are beneficial] provide Evolution, so not at all.
Can mutations be beneficial?
They can certainly be either. When researching it closely scientists have found a lot of mutations which don't seem to have any influence. "Bad" mutations tends not to be functional, and often disappear pretty much by themselves one way or another.
Why are most mutations harmful?
Changes to DNA (mutation) are not necessarily harmful. Species are essentially a conglomeration of mutations which result a vast array of beneficial characteristics. Detrimental mutations generally result in death during early pregnancy, others may predispose an individual to death by cancer or disease at an early age and still others have a dramatic effect on the life of the affected individuals. Breeds of domestic animals are great examples of how many mutations there are within a species that are not specifically harmful. (There are over 500 breeds of dog for example.)
What percent of mutations are lethal to a cell?
"...999/1000 are harmful or fatal and the remainder may be beneficial. (Remine, The Biotic Message, page 221."

What is beneficial mutations?
Well, there is no specific type of mutation that is beneficial. They can be harmful, helpful, or have no effect at all.
What will occur to the genes over generations of offspring that can be beneficial harmful or neutral?
Mutations
What will occur to the genes over generations of off-spring that can beneficial harmful or neutral?
Mutations
Why do mutations tend to be harmful instead of helpful?
Not all mutations are harmful. The improvements in creatures through evolution are from beneficial mutations. The beneficial mutations increase the creature's chance of survival and passing along those new beneficial genes to its offspring.
How does natural selection affect variation?
Variation naturally occurs in populations as new traits arise from random mutations. However, through natural selection only those traits that are beneficial to the organism are passed on to the next generation. Any harmful mutations are naturally weeded out.
Is mutation always harmful for human body?
No. Although there is a chance of a beneficial mutation, the chance of it occurring is almost astronomical. Most mutations are harmful to humans.

Why all mutation are not necessarily harmful?
Mutations are changes in DNA. Most are neutral or beneficial. Mutations have allowed animals to adapt to new environments and new species to evolve.
