Covalent bonds are formed when two atoms are able to <em>share</em> electrons.
Iroinic bonds are form when two atoms are <em> </em> electrons from each other to complete the bond. This results in a pair of ions.
<u>Covalent bonds:</u>
- Have a definite shape.
- Have a low melting point.
- At room temperature they are in a liquid or gas.
- They occur between two non-metals.
<u>Ionic bonds:</u>
- Have no definite shape.
- Have a high melting point.
- At room temperature they are solid.
- They occur between a metal and a nonmetal.
Answer:
100% red kernel color
Explanation:
R_B_ = Red kernel color
R_bb and rrB_ = yellow kernel color
rrbb = white kernel color
True breeding red kernel x true breeding white kernel = RRBB x rrbb
F1 genotype ratio = 100% RrBb
F1 phenotype ratio = 100% red kernel color plant.
<em>The expected phenotype of the F1 plant is 100% red kernel color.</em>
