The theory is an evolutionary concept that suggests that behaviors that an organism survive are passed on while weak behaviors are lost.

In population genetics, Gene Flow (also known as gene migration) is the transfer of alleles or genes from one population to another. Migration into or out of a population may be responsible for a marked change in allele frequencies (the proportion of members carrying a particular variant of a gene).

Its genetic flow hope it helped

If the experiment was perfomed more then once and you get the same results
