The sum of both allele add up to one or one hundred percent for that population. To calculate the frequency we use There are five conditions in order satisfy the Hardy-Weinberg equilibrium. These are, mutation, gene flow, genetic drift, non-random mating and selecting. Evolution does not occur in individuals, it occurs in a population. Charles Driven theory of natural selection states that natural selection acts to preserve and accumulate minor advantage to any trait that helps them to Bette suited…...

The data was found using a program called Popsicle (Heron 2002), which picked genotypes Mandalay, and showed the results after particular conditions were entered. Students took these numbers and visually displayed them in charts. They configured the predicted amount of adults for each genotype by using the Hardy- Weinberg mathematical equation pa + PC + q to figure out the expected adults for the genotypes AAA, AAA, and AAA. The students also produced graphs showing allelic frequencies and genotype frequencies.…...

Since males are motivated to maximise their reproductive success also, they need to first display their willingness and ability to provide what the ‘choosy’ female needs, from which they may be selected as ‘suitable’ – this is known as INTRA-SEXUAL selection, whereby males must compete amongst themselves to be ‘selected’ by the female i.e. the female has evolved to become the choosier of the sexes, since she has more to lose. However, the male, in attempting to maximise his reproductive…...

These two concepts relate because of their common…...
