slide 1 of 5. A polygenic trait, is a trait that nonallelic genes control. These traits result from one or more genes contributing to the phenotype. An individual's physical appearance is determined by chromosomal inheritance and genotypic ratio. This phenomenon is known as Mendel's Laws of Inheritance.
, cycle. Water molecules continuously move from location to location in this cycle. The water cycle is important to weather and climate and, ultimately, to all life on Earth. The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.
The water cycle, is a naturally occurring cycle which purifies and renews the Earth's water. Usually starting with evaporation, the water is turned into steam and lifted to fo â¦ rm clouds which then come back down in the from of precipitation. Then the precipitation runs off surfaces into drainage basins, underground water sources or large bodies of water. Then they are again evaporated and the cycle continues.
