What is polygenetics ?

Explanation:

is a member of a group of non epics tactic genes that interact additively to influence a phenotypic trait

Answer (three definitions, where two are biology and one is geology):

1) (biology) Of or pertaining to polygenesis; polyphyletic.

2) relating to or determined by polygenes.

If you don’t know what a polygene is: A polygene or multiple gene inheritance is a member of a group of non-epistatic genes that interact additively to influence a phenotypic trait.

3) (geology) One which is composite, or consists of two or more monogenetic ranges, each having had its own history of development.

Hope this helps! :)

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
