|
|
|
Offspring do not possess exact copies of parental DNA
|
|
|
DNA of only one parent is copied and passed on to the offspring
|
|
|
Offspring are formed at different times
|
|
|
DNA of parent and offspring are completely different.
|
Detailed explanation-1: -So, the correct option is ‘Offspring do not possess exact copies of parental DNA’.
Detailed explanation-2: -Yes, vegetative reproduction is asexual reproduction and clone is also an offspring of asexual reproduction. The clones are formed from the same group cells. They are genetically similar to their source and each other.
Detailed explanation-3: -Most multicellular organisms undergo reproduction by sexual means, which involves genetic hybridization of two individuals (parents), making it impossible to generate an identical copy or clone of either parent.
Detailed explanation-4: -More narrowly, a clone can be defined as an individual organism that was grown from a single body cell of its parent and that is genetically identical to it.
Detailed explanation-5: -Do clones ever occur naturally? Yes. In nature, some plants and single-celled organisms, such as bacteria, produce genetically identical offspring through a process called asexual reproduction. In asexual reproduction, a new individual is generated from a copy of a single cell from the parent organism.
