    Population Genetics / Hardy-Weinberg Problems Directions: Work out the following problems on a separate piece of paper. Show ALL work and circle your answers. 1) If the frequency of a recessive allele is 30% in a population of 100 people, how many would you predict would be carriers of this allele, but would not express the recessive phenotype? q= 0.30 p= 0.70 Carriers = 2pq = 2(.3)(.7) = .42 #= (.42)(100) = 42 individuals 2) From a sample of 278 American Indians, the following MN

    an inaccurate genotype to be found when testing the 5-HHTLPR polymorphism. This study contains a large amount of statistical reasoning and proves significant correlations between some of the variables using measurements that can be used again having the same results. Measurement validity refers to the accuracy of the measurements among the variables and is another strength when evaluating this study. This study contains detailed and extensive measuring tools when measuring the genotype, ADHD-related

    persistent in the class that was expected was going to be near 95% (Curry, 2013). However, such a high percentage was not found. Of the class, only 49.3% of individuals were determined to possess a genotype that results in a phenotype of lactase persistence. Conversely, 40.8% of the class was found to carry the genotype lct/lct which results in the phenotype of lactase non-persistence. Therefore, the results are nearly 50% off from what we expected initially. This could be for numerous reasons, but perhaps

  • Attention Deficit / Hyperactivity Disorder Case Study

    794 Words  | 4 Pages

    Attention-deficit/hyperactivity Disorder (ADHD) is a behavioral disorder with a complex etiology. Demonstrating a high genetic basis of ADHD symptomatology, several studies have shown an association between this conditions and dopamine-related genes including the dopamine transporter gene DAT1 and the dopamine receptor 4 gene DRD4. Additionally, various environmental factors have been implicated, ranging from pre- and perinatal conditions such as maternal stress and smoking during pregnancy, to many

  • Genotypes Of Bartonella In Kenya

    985 Words  | 4 Pages

    Kosoy et al. [11] described the presence of Bartonella in 13 insectivorous and frugivorous bat species sampled across 25 localities in Kenya. A total of 331 blood samples were re-suspended in brain-heart infusion (BHI) broth and plated on agar supplemented with 10% rabbit blood, of which 106 (30.2%) were culture positive. Bartonella isolates were obtained from 23 (26%) straw-colored fruit bat (Eidolon helvum), 22 (21%) Egyptian fruit bats (Rousettus aegyptiacus), four (44%) African sheath-tailed

  • Designer Babies: What is Ethical? Essay

    Designer Babies: What is Ethical? Imagine a parent walking into what looks like a conference room. A sheet of paper waits on a table with numerous questions many people wish they had control over. Options such as hair color, skin color, personality traits and other physical appearances are mapped out across the page. When the questions are filled out, a baby appears as he or she was described moments before. The baby is the picture of health, and looks perfect in every way. This scenario

  • Genetic Engineering: Designer Babies Essay

    690 Words  | 3 Pages

    Imagine a parent walking into a conference room; a sheet of paper waiting on a table with a lot of different questions on it. Things that many parents wish they had control over. Options such as hair color, skin color, personality traits and other physical appearances are placed out across the page. When they fill questions out, a baby appears as it was described just before. The baby is in the picture of health, and looks perfect in every way. The use of genetic engineering shouldn't give parents

    emotional triggers. Due to its bi-directional connections to limbic structures, as well as the large number of glucocorticoid receptors present within its pyramidal cells, the hippocampus (HC) is the main region of interest when considering stress genotype and phenotype. An enormous variety of proteins expressed within this highly significant structure have been the focus of modern research activities – including various cytokines, cell adhesion molecules

  • Notes On Phenotypic Plasticity And Local Adaptation

    1384 Words  | 6 Pages

    Phenotypic Plasticity Phenotypic plasticity is when a genotype of an organism displays different phenotypes due to the conditions of the environment. It is important to understand why different organisms respond differently to changes in the environment and the ways they adapt to these changes. This paper focuses on whether these adaptations are due to either phenotypic plasticity or local adaptation. Since nothing is ever perfect, the paper also concentrates on the constraints of phenotypic plasticity

  • Plants Live Or Die Depending On Their Genetic Makeup ( Genotype )

    1712 Words  | 7 Pages

    Plants live or die depending on their genetic makeup (genotype). Albinism in plants is caused by a genetic mutation that can occur in both seedlings and matured plants, preventing the process of photosynthesis. This is because in albino plants, the genetic blueprint for making chlorophyll is absent. The chemical formula for photosynthesis is: CO2 + H2O → C6H12O6 + O2 + H2O Plants photosynthesise to sustain themselves, using chlorophyll and sunlight to convert carbon dioxide and water into glucose
