How do differences in air pressure affect the air around us?

Differences in air pressure also in wind.

Explanation:

Air moves from areas of high pressure to areas of low pressure and the greater difference in air pressure, the faster the wind blows. As you travel further from the Earth's surface, the atmosphere changes.

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