Solution

The correct option is C Offspring do not possess exact copies of parental DNA
During sexual reproduction, fertilization creates a single-celled zygote which includes genetic material from both gametes. In a process called genetic recombination, genetic material (DNA) joins up so that homologous chromosome sequences are aligned with each other, and this is followed by an exchange of genetic information. Whereas, cloning is the process of producing genetically identical individuals of an organism either naturally or artificially. In nature, many organisms produce clones through asexual reproduction.
So, the correct option is 'Offspring do not possess exact copies of parental DNA'.
