How does a mutation change an organism? When do such mutations occur?

Sometimes, before the cell divides, a mistake made in the DNA is copied to make a new set of chromosomes. This is called mutation. If a mutation occurs during the formation of sex cell, an offspring that results from that sex cell will be affected by the mutation. Even though some mutations don't make a difference and some are even helpful, many mutations are harmful because they can change the instruction of the gene.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
