Web26 jul. 2024 · Horizontal gene transfer can be defined as the transmission of genetic material between evolutionary lineages by some means other than fertilization. Evidence of horizontal gene transfer (HGT) was initially observed as early as 1928 (Griffith, 1928 ) when virulence was shown to be transferred between pneumococcal strains in mice. Web24 apr. 2024 · Gene flow differs from genetic drift because it is the transfer of alleles or gametes from one population to another. It happens when a population migrates or becomes geographically isolated. This is different from the genetic drift seen with the founder effect where the new group is formed in an area that does not have an existing population. michael searingWeb4 dec. 2024 · Horizontal gene transfer within diverse bacterial populations occurs through multiple mechanisms of exchange.
