Why, during sexual reproduction in daughter organisms, new signs are always observed that were not in parental individuals.

New signs appear because germ cells divide through meiosis, and in the process of meiosis, chromosomes merge (conjugation) and exchange sites (crossing over).
Thus, chromosomes exchange genetic material with each other and acquire new characters, which are then received by the daughter organism.
During sexual reproduction, the offspring is always genetically different from the parents; it is born genetically unique.
The child organism will be genetically identical to the parent, only in asexual reproduction (budding, division, vegetative reproduction and reproduction by spores).
