Question

For natural selection to occur, variation must exist. This is true because without variation, there is no way for change to occur between generations. Traits are never inherited by offspring. There is no competition among individuals. The one trait that exists is always advantageous, and change is not necessary. Even though natural selection was named after the artificial selection that plant and animal breeders use, it really refers to the variable ability of species to survive and reproduce. Reproduction of traits from generation to generation. Selective retention of variation in a population. Survival of the physically fit. Darwin believed that when a new species arises, it does so by gradually accumulating small changes. Immediately achieving a distinct, discontinuous form. Following God's will. Achieving perfection through natural selection in the first try. What does Mendel's second principle (of independent assortment) state? Transmission includes both blending and particulate inheritance. Eggs and sperm are formed independently of one another. The inheritance of one trait does not affect the inheritance of another trait. Particles inherited from the mother are more likely to be transmitted to female offspring, and particles inherited from the father are more likely to be transmitted to male offspring. An organism expresses antipredator tactics regardless of the number of predators in the environment. This is an example of behavioral plasticity. Behavioral mimicry. Behavioral canalization. Behavioral localization.
