why is no variation seen in clone
Answers
A new study of plants that are reproduced by 'cloning' has shown why cloned plants are not identical. Scientists have known for some time that 'clonal' (regenerant) organisms are not always identical. Now researchers believe they have found out why this is the case in plants: the genomes of regenerant plants carry relatively high frequencies of new DNA sequence mutations that were not present in the genome of the donor plant
Answer:
Explanation:
Clones are simply identical genetic copies. Many organisms reproduce through cloning as a matter of course, through a process called asexual reproduction. Bacteria, yeast, and single-celled protozoa multiply by making copies of their DNA and dividing in two.
The same, but different. The great misunderstanding with clones is to assume that they are genetically identical to the organisms being cloned, and will therefore be phenotypically identical to them. These differences can originate significant differences in the operation of the clone's genes with respect to the donor.
