B Allele Lab Report
The simulation experiment is intended to investigate the shift in population allele frequencies in response to selective pressure. We do not grow live populations and test them in our class due to the fact that we don't have enough time. Also the populations have to go through generations which cannot be conducted in a classroom as a result of not being enough room to reproduce, and the organisms would not be in their natural habitat leading to the cause they might not even try to reproduce.This procedure is different among the three populations because in each population there are either no changes, there are either changes only to the homozygous recessive allele set, or changes to the homozygous recessive allele set and half of the homozygous …show more content…
As each generation passed the allele frequency for b decreased from the previous generation because after each generation the homozygous recessive (white) allele set was removed from the population and not returned. The graph was wide and the lines were far away from each other as a result of the B allele having a high frequency and the b allele having a low frequency rate. I predict that the B allele frequency would be 0.76 and the b allele frequency would be 0.24 for the next generation. The B allele frequency would be 0.82 and the b allele frequency would be 0.18 for the next ten generation because the b allele frequency would decrease and the B allele frequency would …show more content…
A real world example similar to the scenario of population 2 is cystic fibrosis which is often fatal prior to the reproductive age. A real world example similar to the scenario of population 3 is sickle cell in accurate conclusion anemia which is among people and malaria infested tropical locations. Homozygous recessive sickle cell is fatal while the heterozygotes is not usually lethal as it affects individuals health but also offers protection from malaria

    Lab 8: Genetic Analysis

    In Lab 8, we had analyzed remains found at a wooded area near Jonesburg and tried to determine if the bones belonged to a 28-year-old woman who had been reported missing from a city within the vicinity. Upon analysis, it was determined that they did belong to a female. However, it was not possible to determine if the bones did belong to the missing women. Lab 12 presented the opportunity to genetically analyze the remains found. DNA profiling, also referred to as typing and fingerprinting, uses genetic material to show relatedness and uncover the identity of organisms. Most commonly associated with forensics, it can be used in an array of scientific fields such as anthropology. One method that can be used, when a large sample present, is restriction…

    Agar and Media Preparation— Agar plates containing King’s B Agar were often used throughout the experiment to support growth of Pseduomonas fluorescens. A recipe was used that included a mixture of 10g Proteose Peptone #3, 1.5g Potassium Phosphate Dibasic (K2HPO4), 30ml 50% Glycerol, ~965ml water and 20g agar. The mixture, post- autoclave, was left to cool and 5ml 1M Magnesium Sulfate (MgSO4) was added and created about 40 plates. King’s B Medium was made using the same procedure as the King’s B Agar with the exception of adding 20g of agar. These recipes were referred to later in the protocol to create additional plates and liquid cultures when growing multiple strains.…

    A gene pool is the configuration of the sum of the alleles of each individual in a population. A comparison of the genotype frequencies from one generation to another indicates whether evolution has occurred. Gene pools that are not evolving are said to be in the Hardy-Weinberg equilibrium (Campbell 456). The main objective of this human population genetics experiment was to examine the allele frequencies for the sample population of my biology class and predict genotype frequencies. I wanted to calculate the proportion of individuals in the sample population with ALU inserts to determine whether the insert is in the Hardy-Weinberg equilibrium. ALU inserts are small, repetitive sequences of DNA distributed through the genomes of primates. ALU inserts from human chromosome 8 of the tissue plasminogen activator (TPA) gene were selected because they are unwavering and reliable genetic markers, as most of them show no signs of being subject to disappearance or repositioning (Batzer 12288). My hypothesis was that the ALU insert would be in the Hardy-Weinberg equilibrium because the five assumptions for the equilibrium of random mating, a large population, and no selection, mutation or migration seem to correlate with respect to the ALU insert in this random and diverse sample…

    After the conference, I learn that quantitative human traits are easily quantify because of the continuous distribution in a population. Some example are height, weight, blood glucose level and common disease which are model by a bell shaped curve where most people falls in the average region. In the flipping pennies model, polygenes are addictive or cumulative and reassortment is the mixing of genes and genetic material from parents into new combinations of genes in their offspring. Polygenes reassert every generation yielding thousands of new and unique possibilities. I also discover that in human genetics, there are variants meaning millions of differences among individuals in a population. One type of variants is the Single Nucleotide Polymorphism or SNPs which is found in greater than 1% of the population. Another variants is Copy Number Polymorphisms or CNPs also found in greater than 1% of the population. This mean that we all technically 99.6% identical in our DNA sequence and only .4% is where we are different cause by the variants. Stems cells are capable of becoming another more differentiated cell type in the body. It has a unique ability to self-renew with unique…

    Population geneticists study frequencies of genotypes and alleles within populations rather than the ratios of phenotypes that Mendelian geneticists use. By comparing these frequencies with those predicted by null models that assume no evolutionary mechanisms are acting within populations, they draw conclusions regarding the evolutionary forces in operation. In a constant environment, genes will continue to sort similarly for generations upon generations. The observation of this constancy led two researchers, G. Hardy and W. Weinberg, to express an important relationship in evolution. The law that describes this relationship bears their names. The Hardy-Weinberg Equilibrium Theory serves as the basic null model for population genetics. Every individual has alleles that were passed on from their parents. If we take all of the alleles of a group of individuals of the same species (that is, a population) we have what is called the gene pool. The frequency, or proportion, of individuals in that population that possess a certain allele is called the allele frequency. Populations can have allele frequencies, but individuals cannot. This obviously makes populations the best hierarchical unit, or level, to study evolution, as evolution is basically the study of the change in allele frequencies over time.…
