g If the two genes are on the same chromosome and are completely linked (no recombination ever occurs between the genes during meiosis), what phenotypic ratios would you expect to find in the F2 generation

1 : 1 : 1 : 1.

Explanation:

If the two genes are on the same chromosome linked to each other and no recombination ever occurs between the genes during meiosis, then the phenotypic ratios will be 1 : 1 : 1 : 1 in the F2 generation. 1 : 1 : 1 : 1 is the phenotypic ratio in which the alleles of the two genes assort independently into gametes and no non-parent phenotype is produced because of no recombination of genes occur. Recombination of genes is responsible for the gametes different from both parents.

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.
