  • Drosophila Melanogaster: A Genetic Analysis

    Introduction Drosophila melanogaster can be considered model organisms for the study of genetics. Some characteristics that contribute to this status are their quick lifecycles, large amount of offspring, and the presence of only four chromosomes. Drosophila melanogaster contain bristles on the thorax, head, legs, and abdomen. These bristles are used as a sensory mechanism, allowing fruit flies to detect their surroundings as they fly and walk around their environment (Yehuda, 2011). The rate…

  • Mendel Biography

    Johann Mendel was born on July 20, 1822 in Heinzendorf bei Odrau, a small village in the Austrian Empire. Mendel’s parents were poor farmers who made many sacrifices to pay for his education. Mendel did well throughout his high school career and, at age 18, he entered the University of Olomouc in 1840. During his time at the University, Mendel studied mathematics, philosophy, and physics. In 1843, at age 21, Mendel experienced financial troubles. Professor Friedrich Franz, a physicist,…

  • Exercise 3: What Is The Genotype Of The Mother?

    dominance, or codominance? Why does the mother have freckles, even though she has a gene for no freckles? Why does the father have no freckles? | Freckles in humans are a dominant recessive pattern. A parent carrying even a single copy of the dominant allele F will have freckles, in this case it is mom. The dad who has homozygous recessive ff has no freckles. | Exercise 3: Blood Type A male has Type A blood, and a female has Type B blood. Could they have a child with Type O blood?…

  • Kitten's Genetic Differences

    the kitten’s two alleles comes from the father and the other comes from the mother. There are two possible alleles for that gene, a dominant one and a recessive one. The kitten’s physical appearance is known as their phenotype, and whatever alleles the kitten has is known as their genotype. If the kitten’s genotype is two dominant alleles, then that’s what their phenotype will be. This is known as having a homozygous genotype. If a kitten’s genotype is the the two recessive alleles, then that is…

  • Confirmation Of Mendel's Law Of Segregation

    Confirmation of Mendel’s Law of Segregation I. In Biology class the past few weeks we have been learning about Gregor Mendel. Gregor Mendel is often called the father of modern genetics. Mendel developed the theory of inheritance several decades before the observance of chromosomes via microscope. In Biology lab the past two weeks I completed a series of tests using fast plants, Brassica rapa. The objective of this experiment was to study the Mendelian laws of genetics as they applied to…

  • Punnett Squares Lab Report

    mouse passes a dominant allele, the offspring will have black fur.” Having this hypothesis allows us to begin the experiment and come to the conclusion as to whether or not the results will either support or refute the hypothesis. For the first part of the experiment students are to predict and confirm the offspring of two mice homozygous for black fur. Now, in order to proceed identifying an unfamiliar term is key. Homozygous refers to having the same or identical alleles. With this in mind,…

  • Lactase Lab

    Lactase persistence is the result of a gene mutation and therefore considered the mutant allele while non-persistent is the wild-type allele. However, the LCT gene itself is not mutated. The single base pair mutation (a change from a “C” to a “T”) occurs in an intron of a neighboring gene that lies 13,910 nucleotides upstream, which alters the process in which the…

  • Albinism Essay

    Albinism is a rare genetic condition characterized by the reduced pigmentation in a person’s hair, skin, and eyes. In most variations of the disorder, it is an autosomal recessive condition, an albino individual would have to inherit the recessive allele from both parents. This condition has been of particular intrigue to me ever since I had been introduced to the disorder when reading a novel where the main character suffered from albinism. Even though this character had suffered extreme…

  • Gregor Mendel's Laws Of Inheritance

    and Law of Dominance (Orel, 1996). The Law of Segregation states two alleles for a heritable character separate from each other during gamete formation and end up in different gametes (Reese et al., 2013). Law of Independent Assortment states that each pair of alleles separates independently of each other pair of alleles during gamete formation (Reese et al., 2013). Mendel’s last law, Law of Dominance, states that recessive alleles…

  • Protein Synthesis Essay

    In protein synthesis there are 3 to 4 structures that occur. In the primary structure there are covalently bonded sequences of amino acids and this happens through dehydration synthesis where complex molecules are broken down to simple components. Secondary structure happens within the protein and can repeat multiple times and this happens from the folds by the Hydrogen bonds. Finally, you reach tertiary structure where the final 3-dimensional shape is shown by the complete polypeptide chain.…
