    Name: Desire Salazar Date: 12/15/17 Period: Pre-AP Biology 5th Title: Population Genetics and Evolution Problem: How does the Hardy-Weinberg law provide evidence of evolution? Background Information: The lab will determine how the Hardy-Weinberg law provides evidence of evolution in a population. A population is “a group of organisms of one species that interbreed and live in the same place at the same time” (Biology Online). In each population, are three key elements: size, density, and dispersion. In a population, size is extremely important because it determines its ability to reproduce. If the population is too small, then the community living there will most likely not be able to reproduce very well. Population density is the amount of…

    The results of the statistical comparison of genetic variability between the wild and founding population suggests that because the assumption figure is less than 0.5 (see table 2) the null hypothesis could not be dismissed. This meant that there is was no difference between the wild and founding population’s genetic variability. In relation to conservation biology, this finding is rather optimistic. Due to the fact that the two populations genetic variability is close to one-another allows for…

    SNPs are nucleotides that bond with complementary pairs. Due to microevolutionary forces such as gene flow and the founder effect, the alleles increase over time. The founder effect measures the percentage of alleles in small populations. Based on observing the skulls, Neanderthals have similar features to the Homo heidelbergensis. For example, the Neanderthal populations emerged based on the unique sequence of SNPs. There are multiple mutations, which creates new alleles at particular locus and…

    evolutionary change requires for the process to affect the allele, gene variant, frequency. Natural selection is one of these mechanisms. The process of natural selection comes down to variation, differential reproduction, and heredity. In other words, natural selection occurs when there is a variation in traits and one of those traits makes it more likely for individuals with that trait to survive and reproduce, allowing them to pass down that trait to a new generation. Natural selection could…

    Inbreeding in captive populations of animals also occurs, and is generally done intentionally for various reasons. Animals can become inbred as a result of selective breeding for desirable traits. Animals in captivity face different selection pressures in comparison to those in the wild, as they are provided with optimal environmental conditions and have the natural ability to choose a mate removed. Breeding solely within a single captive population of animals eliminates the addition of…

    Charles Darwin and Malthus: In “An Essay of the Principle of Population” Malthus proposed over population will lead difficulty in survival, which was majorly supported Darwin’s natural selection. Darwin found that organisms will most like fight for survival under environment pressure. Kimura and Sewall Wright: Kimura inspired the works of Sewall Wright, J.B.S. Haldane, and Theodosius Dobzhansky. He studied mainly Sewall Wright’s work, and taught himself the complicated math that needed for his…

    at work then there would be a loss as to one of the ways that we understand how we all came to be. “Evolution is the change in allele frequencies of a population, which over time produces a population with new or modified characteristics. (Evolution: The Big Picture)” Evolution can be achieved through four different methods: mutation, genetic drift, migration, and natural selection. Out of the four methods, natural selection is most important. Charles Darwin describes natural selection in his…

    specific traits on to their offspring, otherwise known as heredity. The purpose of this is so that succeeding generations will have the ability to differ slightly from their own parent 's generation. This could be end up making them more suited to the environment they are surrounded by and better able to survive. Throughout history, every part of an individuals body has been acted upon by descent with modification. When Darwin was sailing around the globe and exploring the Galapagos Islands, he…

    Measurable Outcomes 1. Describe and demonstrate knowledge of modern evolutionary synthesis, natural selection, population genetics, micro and macroevolution, and speciation. I learned about the speciation of animals in Module 3 and in Module 4 I learned about modern evolutionary synthesis, natural selection, population genetics, and mirco and macroevolution. I was able to learn all this information due to the chapter 46 and chapter 47 notes, the online textbook, and the PowerPoint notes. This…

    Reporting: - The author emphasize on how the race and genetics are used to calculate the variation and how the within human population is more varied than between human population. Author also uses the statics and graphs to explicate that how racism is followed through genetic ancestry and lead into the health disparities (JADA BENN TORRES, 2007). Responding: - According to my point of view, Relating: - As per the knowledge I have regarding the issue, it totally contradicts to the recent…
