Primary School Biology 5 points. What is the source of genetic variation in asexually reproducing organisms.
Ask for details Follow Report by Shrishtika Log in to add a comment. In asexual organisms variation can occur from a variety of sources - mutations, homologous recombination and plasmid transfer.
Mutations occur at a rate of roughly one base per million, meaning you would get between 0.
Depending on the actual mutation these can show anything from no changes to a significant effect. Homologous recombination occurs when reproducing a chromosome, it allows the crossing over of sections so a mutation can end up in one offspring as opposed to the other, changing the effects. Finally plasmid transfer allos exchange of small DNA structures between bacteria, hurrying along factors such as antibiotic resistance. In sexually reproducing organisms there are mutations and the crossing of gametes.
