Acoustic energy is sound energy produced by vibrating objects. The definition of sound says that it is a disturbance of energy that comes through matter as a wave, and that humans perceive sound by the sense of hearing. Sound pressure is the effect and sound power (energy) is the cause. But our eardrums are only sensitive to the sound pressure, and so are microphone diaphragms.
Polygenic inheritance. Definition. noun. A non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes. Supplement.
Multiple gene (polygenic) inheritance explains many plant and animal traits where there is a wide variation between extreme phenotypes, with most individuals having intermediate phenotypes. Some examples of polygenic inheritance are: human skin and eye color; height, weight and inteligence in people; and kernel color of wheat. In fact, kernel color in wheat is nicely shown in Table 2. Table 2 is essential the same as Table 1, except the extremes in color are dark red and white, rather than black and white.
