G.H. Hardy and Wilhelm Weinberg created the Hardy-Weinberg principle, which states that a population will remain in equilibrium (with no evolution - the traits all stay the same) if the following five things are all true. 1. No mutations in the population 2. No gene flow between populations 3. No genetic drift in the population 4. No selection (sexual or natural) for traits 5. All mating (of males and females within species) is random and not based on attraction Write a paragraph (or series of paragraphs) in support of this principle. Explain why these five factors are essential to the process of evolution. Be sure to discuss each of the five at least once throughout your paper. You can start by defining each condition and you can then continue to describe the relationship between them. Note: If you would rather submit a video (with your voice) or an audio file where you are responding orally, you may do this instead of writing series of paragraphs.
Gene Flow
Gene flow, also known as gene migration, is the introduction of genetic material from a particular population to another population of the same species through interbreeding. For example, a bee facilitates its reproductive process by carrying pollen from one flower to another. The flow alters the composition of the gene pool of the receiving population. It introduces new alleles within the population and helps increase variability. This exchange of genetic material occurs through reproduction and brings about new combinations of traits into the population. Where human beings are concerned, actual migration of populations, whether voluntary or forced, brings about gene flow.
Population Biology
Population biology is the study of patterns in organism populations, specifically the growth and management of population size, population genetics, the evolution of life history, species interactions, and demography.
Speciation
The process of speciation involves the formation of new species during evolution. The new species evolve in such a way that both new and old species are not able to interbreed. Thus, speciation occurs when few members of one species get separated from the main species due to geographical, mechanical, or reproductive isolation. These separated members develop new traits that make them different from the main species. In other words, speciation could be defined as the absence of gene flow between two populations that become new species.
Allele Fixation
A gene is a unit of heredity and contains both physical and functional information that shapes an individual. Genes are made up of DNA (deoxyribonucleic acid), which carry genetic information from one generation to another, from one set of parents to their offspring, and so on. Every cell in a human body, or any living organism, has the same DNA, which implies that every cell in an individual’s body has all the information it needs to build and sustain the body!
