were counted and put into a genotype frequency equation of to get a percentage. The Hardy-Weinberg equation was then used to determine the genotypes frequencies that were expected in a population at equilibrium. The class data was entered into the Allele Server database (http://www.bioservers.org) where a chi-square test was used to compare observed genotype frequencies with those predicted by the Hardy-Weinberg equation. The data was then compared to genotype frequencies in world populations‚ where

Microevolution -Mutation -Non-random mating -Genetic Drift -Natural Selection -Gene Flow Hardy-Weinburg Theorem: Frequencies of alleles and genotypes are preserved from generation to generation in populations that are not evolving -p2 + 2pq + q2 = 1 Hardy-Weinburg tells us that we will never get rid of bad genes and it’s used to figure how gene populations change over time The Hardy-Weinberg theorem describes a pop’n that is not evolving. It has 5 assumptions: 1. Genetic Drift: This

Premium Genetics Allele Gene
Explain the structure and inheritance of genes (15 marks) A cell’s nucleus contains chromosomes‚ which are long‚ coiled packaged and organized chromatin (molecules of DNA). Chromatin is a complex of molecules found in cells‚ consisting of DNA‚ protein and RNA. Proteins are polypeptides (a large sequence of amino acids). The chief protein component of chromatin are histones‚ which package and order the DNA into structural units called nucleosomes in order to fit in the cell‚ as well as reinforce the

samples to determine the presence or absence of the dimorphic Alu sequence in a class population. A bioinformatic allele server was then employed to calculate genotypic and allelic frequencies of the Alu element in the class population. The Hardy-Weinberg equation was also applied to individual data to produce class data for allelic and genotypic frequencies. Analysis of results and comparison to a larger population showed that those homozygous positive and possessing the sequence are in the smallest
