WebGenes are the blueprint for our bodies. If a gene contains a change, it disrupts the gene message. Changes in genes can cause a wide range of conditions. Sometimes a … WebGenetic 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).
