Question

explain how mutations create genetic diversity?

Answer 1

They change the DNA sequence of an organism/organism lineage.

Answer 2

Mutations lead to genetic variation by producing random changes in an organism's genetic code. This causes a different protein to be produced, or none at all. Usually has a negative effect, due to an important protein, e.g. an enzyme, not being produced, so the organism cannot do a certain thing (e.g. digest fats), occasionally makes an organism better able to survive (positive effect). This means that it is more likely to survive and pass the mutated (beneficial) gene on to it's offspring.

Answer 3

@karenmarinavila @xxallmightyxx Most mutations are neutral, not negative with respect to fitness consequences. And, it isn't about surviving, it is all about ability to reproduce and have viable offspring. It doesn't matter how efficient the digestive system is—if they cannot reproduce the mutation will die with that individual.
