Hardy-Weiberg Equilibrium Lab Report
Hardy-Weinberg Equilibrium
One of the most difficult concepts to understand about the process of evolution is how changes in the genetic composition of a population affect the phenotypic composition of a population, and how both ultimately act to allow evolution of the species. Charles Darwin’s theory of evolution emphasizes that populations, not individuals, evolve. The purpose of my experiment was to test the allele and genotype frequencies. Alleles for a gene are represented by letters of the alphabet.
The theory of Hardy-Weinberg states that an allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolution. How to use and understand the punett square. Also, they created a mathematical model which explains five assumptions of the Hardy-Weinberg theory. The theory states that there are no random mating, no mutation, no natural selection, no gene flow and large …show more content…
By convention the dominant allele is always written first.
The five assumptions of the Hardy- Weinberg Theory are:
1. There are no genetic mutations occurring in the population.
2. There is no gene flow
3. There is no gene drift
4. Reproduction is random
5. There is no natural selection occurring
The original proportions of the genotypes in a population will remain constant from generation as long as the five assumptions are met.
Methods
I randomly created 4 offspring (2 for myself and 2 for my partner). Every time my offspring was (aa) it automatically died I had to mate again to replace it. I calculated the allele’s frequencies and the genotype frequencies. Afterwards, I made a table to organize all my data into the initial genotype, number of individuals, genotype frequencies and allele frequencies.
