    Writing Assignment 1: Description of Unknown Mutant Allele Phenotype Subtle differences were observed after comparing all body parts of mutant and a wild type D. Melanogaster. It was discovered that normal venation pattern was disrupted in mutant D. Melanogaster. The phenotype mutation (vein pattern) of D. Melanogaster was identified with a different degree of expressivity in mutant D. Melanogaster; this was achieved by differentiating the single line (longitudinal vein 5) on a wild-type wing…

    Impact of Salt on Seed Germination Introduction Germination is a key event in a plant’s lifetime and controlled by two main factors which are water and salt stress (Yuan et al., 2016 and Vallejo et al., 2010). Salt stress affects plant growth and crop production by causing osmotic and ionic stress in plants. Alonso-Blanco et al in 2009 reported that less study was made on the traits in Arabidopsis thaliana despite the immense genetic variation present in the species and the importance of seed…

    the survival of the fitter individuals of a given population, and therefore the increase in frequency of the genes that produced the adaptive phenotype. For natural selection to occur, there are three conditions that must be met. First and foremost, there must be variation in a population. If no variation occurs, then no individual will have a phenotype that is any more adaptive or maladaptive than another. Second, the variable trait must be heritable.…

    The Effects of Phenotypes on Predatory Selection Pressure Faith Farmer BIOL 107-512 10/15/15 Introduction The purpose of this experiment is to evaluate how different phenotypes influence predation patterns in Dottus variegatus. In nature, observations of animals such as insects and predatory birds indicate that predators select against organisms with phenotypes that do not blend in with their environment. In this lab, dots and their colors represent the species Dottus variegatus and the…

    The effect of being exposed to light effected the phenotype of the Drosophila melangaster. The phenotype frequencies changed for both the red eyed and white eyed fruit flies (Figure 1). In the populations that were in complete darkness, the white and red eyed phenotypic ratio stayed almost constant throughout the whole experiment for both male and female fruit flies, which was shown with a “V” formation (Figure 1). This trend did not continue, though when it came to the phenotypic ratio for…

    types of traits fall under the quantitative traits category of quantitative genetics because they display a range of phenotypic variation that follow a normal distribution pattern. This means that the traits being analyzed do not fall under discrete phenotypes, but instead there is a wide variety of different offspring that can be present across…

    factor to why the peppered moths had to change a phenotype to adapt to their changing environment (Richardson, Urban, Bolnick et al. 2014). As for the selection and gene flow of how the peppered moths were able to survive in a changing environment are examples of how natural selection had to occur for the peppered to undergo a genetic mutation (Saccheri, Rousset, Watts et al. 2008). As well, the decrease of sulfur dioxide within the air reduces the phenotype within the moth to revert back to a…

    Zebrafish is an excellent candidate as a model organism for studying early developmental process. When comparing the results of ethanol it is evident to see the correlation of higher concentration of ethanol exposure would equal to greater defects in the early development of Zebrafish embryos. For the experiment with just alcohol treated ethanol I believe that after 48 hours I will see embryos not be dead, but lack of movement. This will untimely lead to a shorter life if they reach to maturity…

    A genotype is known as the complete genetic makeup of a given organism. Consequently, a genotype is the one responsible for the phenotype of an individual. In eukaryotes, a single genotype is capable of expressing more than one phenotype (observable characteristics). This possibility is because genes can go through lots of differentiation processes like mutation, changes in gene expression and frequency. So, mutations play a significant role in variation. For example, DNA can be affected by the…
