Answer:
Covalent bonds form when two atoms share valence electrons,
while Van der Waals forces cause an attraction between nonpolar
molecules
Explanation:
A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.
Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).

Answer:
50% chance of their son being colorblind
Explanation:
A Punett square for the man’s mom and dad shows that he definitely has colorblindness and his genotype is XcY
A Punnett square for the woman shows she is a carrier for colroblindness and her genotype is XcX
The chance of having a son is 50% and the chance of that son having colroblinness is 50%
