Each shape in the chart represents a different type of atom. Atoms with a line (stick) between them show a chemical bond. Cells A through D tell you whether or not a chemical bond occurs when the atoms combine.
Use the drawing tool to fill in cells A through D in the chart. Show what will happen when the atoms or molecules combine. Use stick models as necessary.

Which combinations form compounds? How do you know?

Which combination is an element? How do you know?

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
