One parent is homozygous cleft chin and the other is heterozygous. MAKE A PUNNET SQUARE to show the propability in their offspring will be heterozygous for a cleft chin.

50% AA and 50% Aa

Explanation:

Punnet square is a tool used to examine the offspring's genotype result of a breeding experiment. We will need to put the genotype of a parent in the row, and other parents at the column. The parent is homozygous(AA) and heterozygous(Aa), the square will be:

                       AA

                 A            A

        A     AA          AA

Aa    a      Aa           Aa

The result will be 50% AA and 50% Aa

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.
