Gregor Mendel is known as the Father or Genetics as he was the first successful person to observes and study and understand the pattern of inheritance of traits in the population for which he selected the Pea plants.
He performed the experiment by crossing the plants with different varieties of traits like the color of the flower, shape and structure of pods and others.
He knew that which plant is responsible for the trait of the progeny as he grew the pure-breeding plants which when were self-fertilized produced the same traits as of their parent and when cross-fertilized determined the trait of the progeny.
Thus, Crossing true breeding plant is the correct answer.
Once the sun's energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun's energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun's energy is reflected back to space by clouds and the earth's surface.
Scientists divide the Earth into three layers based on composition: the crust, the mantle, and the core. These divisions are based on the compounds that make up each layer.
