How does changing the electronegativity of the atoms affect the bond character answers?

Increasing the electronegativity difference between atoms increases the bond polarity.

If you think of electronegativity values as something like magnetic forces you may see the analogy between a “stronger” force and stronger “polarity”. The following chart shows some examples.

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