In corn, purple kernels (P) are dominant to yellow kernels (p). You have a plant with an unknown genotype that has a phenotype of purple kernels. You perform a testcross and find that all of the offspring are purple.
The layout of the solar system, including the Oort Cloud, on a logarithmic scale. Credit: NASA. In the furthest reaches of the Solar System is the Oort Cloud; a theorized cloud of icy objects that could orbit the Sun to a distance of 100,000 astronomical units, or 1.87 light-years away.
The Solar System is located in the Milky Way, a barred spiral galaxy with a diameter of about 100,000 light-years containing about 200 billion stars. The Sun resides in one of the Milky Way's outer spiral arms, known as the OrionâCygnus Arm or Local Spur.f those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies such as comets and asteroids. Of those that orbit the Sun indirectly, two are larger than the smallest planet.
