Can hybrid forms, once in the wild, lead to noticeable changes in the gene pool of wild populations or upset the ecological balance.

To date, such examples are not described in the literature. They are not able to upset the ecological balance, even if a sufficiently large number of hybrid animals get into the wild. Due to the fact that most hybrid forms are infertile, i.e. not able to give prolific offspring. In the process of meiosis, their chromosomes cannot find their homologues. This problem can be solved using polyploidy. But this is not a frequent occurrence. Even if the polyploids fall into the wild, they will not be able to significantly shift the balance.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
