why do humans alter the genetic makeup of certain key organisms?

Sagot :

Answer:

Changes to an organism that are a result of or result in genetic mutation alter the genetic makeup of an organism and can be passed on to the next generation. Mutations are changes in an organism's genetic information that potentially affect the current functioning of that genetic information.

Answer:

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
