The law proves that natural selection is necessary for evolution to occur ("SparkNotes: population genetics," 2014). The conditions set up by the

For any (2) traits/characteristics evaluated, determine the percentages for p square + 2pq + q square = (percentages of homozygous dominant + heterozygous dominant + homozygous recessive).

Individual Phenotypic Results _________________________________
Class Results: Number of Dominant Phenotype __________ = Percentage = __________
Donnetta Tatum Number of Recessive Phenotype __________ = Percentage = __________ Total = _________ q² = _________ % of the class
Therefore q = the frequency of q allele = √ q² = __________
1 – q = p = frequency of the dominant allele ( ) = _________ p = genotype of homozygous dominant = ________ % of the class
2pq = genotype of the heterozygous dominant = _______ % of the class p² + 2pq + q² = 1 = _______ + _______ + _______ = 1 = ________ % + _______ % + _______ % = 100%

6. Discuss/Explain, “in details,” the concept of the genetic drift of a population.
The process of change in the genetic composition of a population due to chance or random events rather than by natural selection, resulting in changes in allele frequencies over time ("Genetic drift," 2008). The effect of genetic drift in large populations is usually negligible whereas in small populations, it predominates ("Genetic drift," 2008). In a small population, genetic drift results in some alleles become more common while others become less common over time ("Genetic drift," 2008).
7. Discuss/Explain, “in details,” the significance/importance of the Hardy-Weinberg in the evaluation of evolution (change) in a given population over a period of time.
Evolution is not only the development of new species from older ones, as most people assume (O, 1997-2012). It is also the minor changes within a species from generation to generation over long periods of time that can result in the gradual transition to
