READ THIS: Notice that natural selection does not refer to indiv Trequency of adaptive heritable traits in a population changes as a result of natural selection. REQUIREMENTS FOR NATURAL SELECTION TO OCCUR: 17a. Assuming that both types of pom-poms are present in the population, what do you think would happen to the pom-pom population if the black forest experienced a prolonged drought so all the trees died and the habitat became red grassland? 17b. Next, think about an alternative scenario. Suppose that natural selection over many generations had eliminated all the red pom-poms in the black forest habitat so only black pom poms survived. After that, a prolonged drought resulted in this habitat turning into a red grassland. Would natural selection for pom-pom color occur? Why or why not? 17c. The above scenarios are showing that in order for natural selection to occur must exist within a trait.

Genetic Variation

Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.

Quantitative Genetics

Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
