horizontal transmissions การใช้

Both vertical and horizontal transmissions are possible.
Mythological phylogenies constructed with mythemes clearly support low horizontal transmissions ( borrowings ), historical ( sometimes Palaeolithic ) diffusions and punctuated evolution.
Because the evolutionary fate of the agent is not tied to reproductive success of the host, horizontal transmission tends to evolve virulence.
PBFD is usually acquired by nestlings from their parents ( vertical transmission ) or from other members of the flock ( horizontal transmission ).
According to evolutionary medicine, virulence increases with horizontal transmission ( between non-relatives ) and decreases with vertical transmission ( from parent to child ).
