Mutations are ___________________

Question

Mutations are ___________________.  
A) random
B) beneficial
C) always lethal
D) always heritable
E) largely predictable

Accepted Answer

Mutations are random changes in the genetic material that can occur spontaneously or due to environmental factors. While some mutations can be beneficial or neutral, others can be harmful, and they do not always result in lethal consequences. Mutations can also be heritable and passed down from one generation to the next, but their occurrence and effects are largely unpredictable. Therefore, A is the best answer.
