What do the amplitude and frequency of a sound wave determine?

The larger the amplitude of the waves, the louder the sound. The faster the vibrations, the higher the pitch (frequency) of the sound.

Explanation:

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
